Coventry Very Light Rail tours its future home

The Coventry VLR on tour in the city centre Credit: Mark Radford PhotographyCoventry City Council’s prototype Very Light Rail vehicle, which has the potential to transform how people move about the city, is set to be moved ready for real on track testing.

Over the last two years researchers from WMG, University of Warwick together with TDi Ltd, have been designing and building the new Coventry Very Light Rail vehicle for Coventry City Council, which will see an electric powered, zero-emissions, lightweight, rail-based public transport system arrive in Coventry.

The vehicle is being moved from NP Aerospace in the city for some static software testing before moving to a dedicated track at BCIMO in Dudley.

The prototype vehicle has done a tour of Coventry so it could see its future operational home. After leaving the vehicle production site in Coventry it stopped outside the Co-op building and the Transport Museum so that the public could get a better view.Caption: The Coventry VLR outside the Transport Museum Arches  Credit: Mark Radford Photography

Councillor Jim O’Boyle cabinet member for jobs and regeneration and Coventry and Warwickshire LEP board director said, “I am really pleased to see the first prototype vehicle out of the factory and on to our city’s streets. Even on a low loader it looks impressive – modern, sleek and of course the fact its battery powered means it’s good for the environment and air quality too.

“Very Light Rail has reached this really important point thanks to all of the researchers, innovators, engineers and manufacturing skills we have right here in the city. And I believe that we can create jobs and opportunities for local people as we lead the Green Industrial Revolution.

“Coventry was the beating heart of the carbon revolution and now with projects like this, UKBIC, our electric bus fleet and our plans for a Gigafactory we will lead the zero-carbon revolution too.Caption: Councillor Jim O’Boyle with the Coventry VLR  Credit: Mark Radford Photography

“On track testing will take some time – but it should prove the concept – and at that stage I expect there to be lots of interest in VLR from other areas of the UK and abroad. This is a very exciting moment.”

Dr Darren Hughes, from WMG, University of Warwick comments:
“It is very exciting for us to see the development of the Coventry Light Rail vehicle move onto the next phase of testing in Dudley, and to see the vehicle in the City which it will one day call home.

“The vehicle has been constructed within Coventry with a reliance on a regional supply chain where possible, showing the strength in depth of local manufacturing. It is a unique vehicle with state-of-the-art technologies including an advanced battery power-train and resilient glazing making it even safer for public use.”

Helen Martin, director of regeneration & enterprise at Dudley Council said: “The Very Light Rail Test Track and National Innovation Centre (NIC) is a key project for our borough. It will offer an innovative and exciting opportunity to provide lower cost local rail connectivity, encouraging shift from private vehicles towards public transport and creating economic benefits in terms of skills and supply chain opportunities.Caption: Inside the Coventry VLR vehicle  Credit: Coventry City Council/William Hunt

“With the test track now completed, we’re looking forward to testing getting underway later this year.”

Darren Smith Head of TDI adds: “The TDI team are extremely pleased with the projects’ progress to date and the local benefits it has enabled. The work our supply chain, including our colleagues at NP Aerospace have engaged in, has produced an outstanding first off demonstrator for this hugely important and innovative project. The future economic benefits, both nationally and locally, this project will bring cannot be underestimated and TDI are very proud to be entrusted to deliver it for our client, WMG.”

James Kempston, CEO, NP Aerospace, comments: “Collaboration on the VLR project with WMG and TDI has been a great success, resulting in an exceptional prototype, which is ready to begin testing. The project has expanded our capability in the prototype vehicle industry and has enabled us to support a significant environmental transport initiative for the people of Coventry. It’s a very positive story for UK manufacturing with the challenges of the pandemic and Brexit and it’s particularly impressive what the team have delivered in just 8 months. We look forward to any future collaborations this may bring to the business.”

The BCIMO centre in Dudley is home to the test track developed as part of the wider research programme, on which they will now test the vehicle on to ensure that it performs as planned. Important trials will include the rapid battery charging system which will allow vehicle power to be replenished in minutes.

The project has been made possible thanks to funding from the Government’s Local Growth Fund through the Coventry and Warwickshire Local Enterprise Partnership (CWLEP) and the West Midlands Combined Authority Devolution Deal.


Solid-state batteries could be made more cleanly by scaling-up flash sintering

· Flash sintering is a ceramic processing technique which uses electric current to intensively heat the ceramic sample internally rather than using only external furnace heating. The process can lower ceramic processing temperatures and durations significantly, enabling ceramics to be co-processed with metals or other materials, and reducing energy use.

· However, the process can result in low quality ceramics due to weaknesses caused by inhomogeneities in the microstructure.

· The origins of these inhomogeneities caused by thermal gradients in the material during flash sintering have been studied by researchers based at WMG, University of Warwick and academic and industrial collaborators, and routes to mitigate the effects of these gradients are outlined.

· Adopting these modified flash sintering routes will enable the wider use of flash sintering in ceramic processing, enabling lower energy production of many useful ceramic products including solid-state batteries.

Densifying ceramics using flash sintering reduces energy use and may be used to improve the viability of manufacturing complex ceramic structures such as those required for solid state batteries by lowering the temperatures and shortening the duration of the heat treatment.

Working in collaboration with academic and industrial partners, researchers from WMG, University of Warwick have published a review of the state of the artPicture: Causes and Effects of thermal and microstructural gradients in flash sintered ceramics of flash sintering focusing on the formation of inhomogeneous regions within the ceramics which currently limit the scale-up potential of flash sintering. The review finds that thermal gradients are responsible for microstructural inhomogeneities and suggests of routes to eliminate or reduce these effects.

The reduction of energy use in the ceramic manufacturing industry is a key step in meeting global emissions reduction targets, as conventional processes require long firing treatments at very high temperatures. Several low-energy processes have been developed over the past decade, with flash sintering emerging as a particularly promising route for densification of materials for use in applications including solid state batteries, thermal barrier coatings, and ceramic joints.

In the paper, ‘Promoting microstructural homogeneity during flash sintering of ceramics through thermal management’ published as part of a special issue of the MRS Bulletin, Gareth Jones and Dr Claire Dancer from WMG, University of Warwick worked with collaborators from the University of Trento, Wuhan University of Technology, Normandie Université, and Lucideon Ltd to review the origins of microstructural variations in different regions of ceramic materials undergoing flash sintering.

Picture: Microstructural development changes with different sintering approaches. Flash sintering produces fine microstructures with very high density with lower energy use than conventional approaches.Differences in microstructural development originate from thermal gradients within the material during processing, and these can be reduced by careful thermal management during the flash sintering process. These include:

· Altering the method for applying electrodes

· Improving thermal homogeneity through insulation

· Tailoring the frequency of the AC current

· Developing contactless methods for applying the electric current - which are currently limited to consolidation of thermal barrier coatings.Picture: Simulation of heat distribution during flash sintering.

The findings of this review provide a roadmap for further research on thermal management in flash sintering, which will accelerate the development of the process for industrial implementation.

Dr Claire Dancer, leader of the Ceramics Group within the Materials and Sustainability Directorate at WMG, University of Warwick comments:

“Lowering ceramic processing temperatures by using techniques such as flash sintering is an essential step for manufacturing complex multi-material structures such as those needed for solid-state batteries, and for lowering overall energy use in the ceramic industry.

“However, the process must produce robust homogenous ceramic materials to be of widespread use. Our paper explains why flash sintering can result in inhomogeneous properties in ceramics and suggests a number of routes to mitigate these effects.”

Anti-microbial poles for public transport to be made in light of Covid-19 pandemic

Anti-microbial poles for public transport to be made in light of Covid-19 pandemicSince the beginning of the Covid-19 pandemic many people have been, or may feel, hesitant about taking public transport, due to the perceived risk of picking up germs from areas such as the grab-poles on trains, buses and trams, which are the principal point of contact.

However, a team including researchers from WMG at the University of Warwick, product designers Transport Design International (TDI), anti-microbial additive developers BioCote and Promethean Particles and the Health and Safety Executive (HSE), led by Derby based manufacturers Composites Braiding Ltd (CBL), will produce lightweight composite grab-poles with an embedded anti-microbial property in their project AMICABLE, thanks to a £480,000 award from the Innovate UK Smart Grant scheme.

The anti-microbial grab poles will be for use in a wide range of public transport applications, such as bus, tram, rail and underground. This should lead to a step-change in hygiene in public transportation and a reduction in transmission of infections of various origins.

Although researchers are currently focusing on public transport applications, there could be the potential for the materials to be used on cruise ships, medical furniture or wherever there are public-facing surfaces.

The teams, from WMG, CBL and TDI have previously worked together on making the materials for the Coventry Very-Light Rail system, and using their expertise from previous projects and concepts already developed for anti-microbial efficacy in sectors such as food packaging and healthcare, they hope to make the new grab-poles within the next 12 months. At the project completion there is an opportunity to demonstrate, for the first time, the new grab-poles directly within new prototype vehicles such as Revolution VLR and the Coventry Light Rail system.

The poles themselves will be retro-fittable, so not only can they be fitted into new vehicles, they can replace current steel poles in existing ones such as buses and the Underground. The project aims to make a range of poles at costs competitive to the current steel ones, however, due to their light-weight material they will be around a third of the weight and will also help with meeting decarbonisation goals by aiding fuel efficiency and manufacturing via lower carbon methods.

Dr Darren Hughes, from WMG, University of Warwick comments:
“As we work in developing future public transport solutions such as the Coventry Very-Light Rail system, the Covid-19 pandemic opened our eyes to the importance of also making transport as clean an environment as possible for passengers. It is clear that a key point of contact for passengers is the grab-poles and other similar structures. Therefore, incorporating anti-microbial grab poles into vehicles could encourage more people to opt for public transport which is generally an environmentally efficient mode of transport.”

James Taylor, from TDI comments:
“TDI specialises in the design of very light weight vehicles and products so the introduction on this new anti-microbial technology in thermoplastic composites for compliant new vehicle interior products is an extremely exciting opportunity”

Steve Barbour, of Derby-based specialists in thermoplastic braiding CBL adds:
“Using in-mould coating impregnation and fibre commingling techniques, anti-microbial particles will be incorporated into the composite rails during the moulding process. Importantly, as the anti-microbial material will be applied during manufacture, it becomes a permanent part of the structure and therefore is expected to be less susceptible to wear. However, when it does reach the end of its life the thermoplastic matrix material will be inherently recyclable, making the grab-poles environmentally friendly.”

By enhancing collaboration between academia and industry and accelerating these transformative technologies these Fellowships will help to maintain and build on the UK’s position as a world leader in AI.”


Early construction of prototype innovative light rail vehicle for the City of Coventry

The Coventry Very Light Rail (VLR) is an innovative light rail system which will be battery powered, lightweight and rail-based.

In March 2019 a 3D simulation of the vehicle was released, and even with Covid-19 lockdowns, the vehicle build is progressing on schedule at NP Aerospace in Coventry.

The front/side view of the vehicle so farOn the 25th November Coventry City Councillor Jim O'Boyle, Coventry Cabinet Member for Jobs and Regeneration, took the opportunity to see how the construction of the prototype, developed by engineers at WMG, University of Warwick for the City of Coventry is progressing.

WMG, University of Warwick have been working with TDI (Transport Design International) to deliver the novel very light rail vehicle, which as demonstrated in the photos is swiftly reaching completion with the driver’s desk and other sub systems now in place. The vehicle is expected to be finished in February 2021 ready for testing at the new rail innovation centre in Dudley.

Dr James Meredith, from WMG at the University of Warwick comments:
“WMG are delighted that the vehicle build is running on plan in spite of Covid-19. The project is an excellent showcase for UK engineering and manufacturing with over 70 % UK content. We look forward to testing the vehicle in 2021 alongside the innovative low cost trackform we are developing in parallel.”

Exterior side view of the vehicle so farCllr Jim O’Boyle, Coventry Cabinet Member for Jobs and Regeneration, said:

“It is very exciting to see the VLR prototype take shape and for the project to take another big step towards becoming a reality.

“VLR will make a massive difference to our city, revolutionising travel and helping the environment. It will help keep our city at the forefront of the new transport industry and help us to attract new firms and jobs to take the city forward. It also helps cement our position at the centre of the green revolution with work such as UK Battery Innovation Centre.

“There has been some amazing work by all the project partners in some very difficult times and I can’t wait to see the next stages and watch it come out of the design rooms and on to our city’s streets.”

Woven Light Rail Design wins Gold at JEC World 2020 Innovation Awards

The BRAINSTORM project, which saw partners from Far-UK, Composite Braiding, TDI and WMG at the University of Warwick create a woven braided BRAINSTORMcarbon fibre composite frame for a Very-Light Rail (VLR), has won gold at the JEC World 2020 Innovation awards in the Category “Railway Vehicles and Infrastructure.”

The JEC World 2020 Innovation awards is the world’s leading international composites show, the awards ceremony took place virtually, and saw researchers working on the BRAINSTORM project take home gold in the category “Railway Vehicles and Infrastructure.”

The Innovate UK funded project started in 2018, and engineers from Far-UK, TDI, Composite Braiding and WMG, at the University of Warwick set out to make a lightweight VLR vehicle frame, which is braided from carbon fibre composites into a series of tubes. They created their first prototype demonstrator frame in May 2019, which drew attention from the then Parliamentary Under Secretary of State and Minister for Business and Industry, Andrew Stephenson.

The frame is unique as it can be easily assembled by adhesive and simple welding, and can be repaired if damaged, and recycled or reused in other structures at its end of life.

Dr Darren Hughes Associate Professor in Materials and Manufacturing at WMG at the University of Warwick explains:

“It is an honour to have won at the JEC World 2020 Innovation awards, we have worked incredibly hard to create an innovative frame offering significant weight-saving that can allow VLR light rail services to operate in a more sustainable way. Reduced mass leads to a lower requirement for power for propulsion and also lowers the stress placed on the track system. This can also open up significant cost savings in light rail systems.”

“The technology also ensures that the vehicle is tough for a long life in service, easily repairable and strong enough to protect the passengers on board.”

Dr Kevin Lindsey of Nottingham based lightweight structural composite components company Far-UK Ltd said:

“To have our achievements acknowledged and awarded is validation of our ongoing research into lightweight structures. The design process that we used allowed the development of the ultralight yet safe structure. We are now ready to take structures such as these into higher volume in our new manufacturing facility.”

Steve Barbour of Derby based specialists in thermoplastic braiding company Composite Braiding Ltd said:

“It is great that the technology we have been developing has helped lead to such a fantastic outcome. Braiding at rates of over a mile a day, we have a highly automated process that is capable of producing high volume, lower cost structural components that are inherently recyclable. It’s fantastic that the potential has been recognised.”

Paul Salkeld of TDI (Transport Design International) based at Stratford-Upon-Avon adds:

“The braiding method can be used with a wide range of materials including carbon, glass, basalt and aramid. We hope this can revolutionise the design of future transport, and are actively involved particularly in the rail sector to produce more economical and environmentally beneficial vehicles.”

Innovative partner awarded contract to develop very light rail trackform

Coventry VLRThe Coventry Very Light Rail project is about to embark on a new adventure, investigating how to create a low cost trackform for the light rail carriages already in development, thanks to £1.5m funding from West Midlands Combined Authority (WMCA), secured by CCC. This project aims to revolutionise affordable public transport in towns and cities.

So far in the Coventry Very Light Rail project, Engineers from WMG, University of Warwick have worked with TDI to design a battery-powered light rail vehicle for Coventry City Council. The long term objective is that it will become an autonomous vehicle that can hold 50 passengers and work like the London Underground system, where there is no timetable and people can hop on and off.

The vehicle will be lightweight in design using a multi-material approach. Due to being battery-powered there will be no overhead power supply, which is both costly and unsightly.

However researchers are now about to embark on their next venture of the VLR project, as they have received £1.5m via CCC to develop a low cost trackform for light rail. Engineers at WMG will work with Coventry City Council and a major French civil engineering company - Ingerop Conseil et Ingénierie.

The ultimate goal of the track project is to design an affordable trackform that can be easily removed and will reduce impact on utilities, saving hundreds of thousands of pounds digging up roads and moving gas, electric, telecommunication and sewage systems, which is currently the process for building traditional tram systems.

Dr Darren Hughes, Associate Professor at WMG, University of Warwick comments:
“The Coventry light-rail project brings together advanced technologies from a number of sectors to deliver a low-cost environmentally-sustainable public transport solution.

“Now that the vehicles have been designed it is time to look at the track they will run on, and with the help of Ingérop Conseil et Ingénierie, we will make it as affordable and environmentally friendly as possible.”

Councillor Jim O’Boyle, cabinet member for jobs and regeneration said:
“Our plan for Very Light Rail has the potential to transform the way people travel. It will be delivered at a much lower cost than traditional trams, a hop on, hop off service part of the green revolution and of course its innovation born in Coventry.

“While the development of the vehicle is progressing well, we also need to innovate in the development of the track and that’s exactly what Ingérop will be able to help with. Experts in this field we will be setting them the challenge of designing track that that can be laid much more quickly and therefore much more cheaply than traditional track.

“Very Light Rail is a really exciting project. Another innovative first for Coventry and this is another important step in its delivery.”

Philippe-André Hanna, Director for International Transport in Ingérop said:

“We are delighted to join the team for the Coventry Very Light Rail. This project is an absolute need for small and medium cities who want to have a modern, carbon-free, rail-based system and cannot afford it today. After the R&D phase, our real goal as on all our projects around the World is to put in place the most sustainable urban transport system for Coventry and many more cities in Europe."

Tim Hackett, Infrastructure Director at Rendel Ltd said:
“We are really excited to be part of this project with our colleagues from Ingérop having already worked together successfully on some high-profile and complex rail projects. We look forward to collaborating on this innovative and technologically game-changing project, providing support from our new West Midlands office.”

WMG staff use 3D printing in the fight against COVID-19

WMG staff use 3D printing to help in fight aganist COVID19A team of WMG academics, technicians and engineers are using their 3D Printing skills, to help in the fight against COVID-19, by producing face shields for NHS front-line staff.

As the supply of PPE became a key issue in the pandemic, technicians Phil Gibbons, Joseph Benjamin and Martin Worrall, and PhD student Kevin Couling responded to 3D Crowd’s call asking volunteers to use their 3D Printing capabilities to produce face shields.

WMG’s nine 3D printers have now been programmed to run around the clock producing more than 400 shields each week.

The first batch of face shields have now been vigorously inspected, cleaned, packaged and distributed to 3D Crowd’s central assembly station in Warwickshire. They will now be sent to organisations running low on supplies.

The team have also managed to order extra materials and will keep the printers running until supplies literally run out.3D printed face shields

Reader Greg Gibbons explains: “Demand for PPE is incredibly high, and we are in a unique position to be able to help.

“We have 3D Printers running in our Degree Apprenticeship Centre (DAC) and we are also planning to open up our Materials Engineering Centre (MEC) to enable mass production of the shields.”

In addition to the work with 3D Crowd, and with funding from WMG Centre High Value Manufacturing Catapult, the team are also working in collaboration with Queen Mary University of London on the development of an injection moulding process for face shield to enable mass production of the frame.

Associate Professor Jérôme Charmet, and Post-Doctoral Research Associate Rui Rodrigues explain: “It is fantastic that we are able to respond to this call and work towards providing the protection to the NHS that is so desperately needed.

“We are now finalising a tool design before we begin production. Once the process is up and running we then plan to transfer manufacture to Andel Plastics, an Injection Mould SME, who will continue with large scale production.”

 


Car batteries can be frozen for safer transportation  

Currently transporting damaged and defective car batteries is an expensive process as they need to be placed in an explosion proof box which costs thousands of pounds, however researchers from WMG at the University of Warwick in collaboration with Jaguar Land Rover engineers have been able to freeze batteries with Liquid Nitrogen.

An explosion proof box to transport a typical Tesla sized battery costs €10,000 and a furtherCar batteries can be frozen €10,000 for the UN accreditation, however, the ability to transport them in plastic containers which cost a couple of hundred pounds has been made more accessible thanks to researchers from WMG at the University of Warwick.

In the paper, Cycle life of lithium ion batteries after flash cryogenic freezing’ published in the Journal of Energy Storage, researchers highlight that cryogenic freezing does not reduce lithium ion battery’s energy capacity or affect cycle or service life, and could be transported in a safer way.

As the sales of electric vehicles increases, there is more concern for the transportation of damaged and defective lithium ion battery packs. Currently, it is an expensive process, as they are put in an explosion proof box that costs €10,000 and a further €10,000 for the UN accreditation, which EV manufacturers are picking up the bill for.

Explosion boxes are used to contain the battery in case it goes into thermal runway, an overheating condition which can lead to violent explosions and toxic gases being released. However being able to cryogenically flash freeze the batteries completely removes the risk of an explosion, and could therefore mean they can be transported safely in a plastic box.

Researchers who were part of the ELEVATE project funded by EPSRC, WMG Centre High Value Manufacturing Catapult, and Car batteries can be frozensupported by Jaguar Land Rover tested the batteries activity before they froze cells with liquid nitrogen and after, they also drove nails through the frozen cell to test the safety of them, and managed to show that their performance was not effected after freezing.

When being transported batteries will have to be kept in a lorry at -35 degrees, however the amount of packaging is significantly less than explosion proof boxes, making the process more sustainable.

Dr Thomas Grandjean from WMG, at the University of Warwick comments:

“Transporting damaged and defective batteries is an expensive and unsustainable process, however being able to freeze them with liquid nitrogen could save thousands of pounds and help electric vehicle manufacturers be more sustainable.

“We tested the batteries in the most extreme abuse conditions, such as driving nails through the cells and inducing external short circuits, proving that the freezing process is effective and safe.”

Department for Transport to give keynote address at WMG’s Very Light Rail Conference

On the 28th November 2019, Steve Berry OBE, Head of Highways Maintenance, Innovation, Resilience, Light Rail and Cableways at the UK Department of Transport will give the keynote address at the Very Light Rail Conference being held at The Slate on the University of Warwick’s campus. He will speak about the potential for Very Light Rail to transform local public transport.

Steve Berry will be joined by industry speakers and academics involved in developing very light rail, including local companies TDI and RDM. They will talk about three projects that are underway across the West Midlands, and discuss why the West Midlands is leading the way in VLR.Coventry VLR

As the UK population continues to grow along with traffic congestion and vehicle emissions, new transport options are needed to create modal shift and encourage people to leave their cars at home.

At present buses and trams (light rail) provide alternatives to private cars, but bus patronage has been falling steadily for many years in contrast to tram ridership which has taken passengers out of their cars. However, tram routes are expensive to construct and can only be afforded by large city conurbations such as Birmingham. That said, Very Light Rail (VLR) may be a solution that medium sized cities could afford.

Very Light Rail is a lower cost, zero emission option for sustainable transport. The technology can be applied to branch lines as well as urban rail (trams). The Coventry VLR scheme aims to reduce the cost through the delivery of lightweight, battery electric vehicles combined with a novel track form, the first system of its kind in the world.

Coventry VLR3D visualisations of the Coventry VLR vehicle were unveiled earlier this year. The lightweight vehicle is fabricated from a combination of steel, aluminium and composite components and will be capable of carrying 50 passengers.

Unlike traditional trams, the Coventry VLR system will not have overhead cables – the vehicle will be powered by an on-board battery which will be rapidly charged at the end of the route. The vehicles will run on a novel prefabricated track form which be easy to install into the road and remove, negating the need to utility companies to relocate their equipment (which is a significant cost in light rail tram solutions).

Currently the system is being designed to meet Coventry City’s needs, but it is expected other medium sized cities across the UK, such as Leicester and Derby, may follow in due course.

Dr Nick Mallinson from WMG, University of Warwick comments:
“At WMG we’ve been working on very light rail technology with a number of industry partners for 5 years. Progress achieved to date recently convinced the Department for Transport that the time is right for a conference to showcase the work and make local authorities, transport planners and industry aware of the potential for very light rail solutions”
