Project No: 10038683
Project title: Axle Mounted Motor For Retrofit To DMU’s To Enable Zero Emissions In Stations
Lead organisation: WABTEC UK LIMITED
Project grant: £59,450
Public description: This project provides a solution to substantially reduce emissions including NOx and PM when
diesel passenger trains are idling.
There are over 3,500 passenger rail vehicles in the UK currently fitted with a diesel engine, the
large majority of these would significantly benefit from emissions reduction, especially in and
around stations, where diesel engines currently continue to idle, or elevated idle whilst stationary,
sometimes for up to 30 minutes at a terminal station. This is a significant contributor to local air
quality issues from NOx, PM emissions etc.
Furthermore, rail vehicles require large amounts of energy and power to accelerate (and therefore
contributing more emissions), and yet, on the approach to stations significant amounts of energy
are “lost” through “braking”.
This project will address both issues by recovering the braking energy during deceleration and reusing it for auxiliary loads in station and traction to accelerate out of station, this will enable diesel
engines to be isolated in and around stations, whilst also reducing the average emissions such as
PM and NOx over a complete drive cycle by up to 35% and operational costs by up to 30%.
Our objective is to develop and integrate a small, low mass, yet high peak torque and peak power,
axle mounted motor, for retrofit and upgrade for DMU/DEMU passenger vehicle applications. This
motor shall enable kinetic energy recovery during the braking application and also provide power to
the trailer bogie wheels whilst accelerating.
This project will enable several key cost and decarbonisation benefits to the railway.
- It shall enable zero emissions, including NOx and PM, in and around the station, by
enabling a DMU to approach, dwell and depart from a station with the engine switched off. - It shall enable a proportional average reduction in all emissions, through reduced fuel consumption resulting from the electrical energy recovery from regenerative braking and re-deployment through auxiliary and traction use.
- It shall enable less brake wear thus reducing particulate emissions from brake pads especially around stations.
- It shall enable reduced operating costs for the train operator through fuel saving, engine/transmission maintenance savings and brake pad saving.
- It will not require any modification to the existing diesel engines or drivetrain and will compliment any other decarbonisation initiatives.
- It shall provide a substantially lower cost and risk solution when compared to any other previous or current hybrid solutions.
My Thoughts And Conclusions
This is a classic simple solution, that could have big benefits.
I suspect, it can also be paired with Wabtec’s other proposal; Zero Emission Powering of Auxiliary Loads In Stations.
25kV Battery Train Charging Station Demonstration
This project was one of the winners in the First Of A Kind 2022 competition run by Innovate UK.
In this document, this is said about the project.
Project No: 10037158
Project title: 25kV Battery Train Charging Station Demonstration
Lead organisation: SIEMENS MOBILITY LIMITED
Project grant: £59,910
Public description: The UK rail industry is committed to decarbonisation, including the removal of diesel trains by 2040.
Replacing diesel trains with electric, hydrogen or battery bi-mode rolling stock provides faster, smoother and more reliable journeys, as well as eliminating local pollution and greatly reducing carbon dioxide. To enable clean, green electric bi-mode operation without continuous electrification requires enhancement of the power supply to existing electrification and novel charging facilities to support bi-mode trains. No small, low-cost solution is currently available for charging facilities that are compatible with standard UK trains and locally available power supplies and space.
Siemens Mobility, working with ROSCO, TOCs and Network Rail, will deliver a novel AC charging solution enabling simple installation of small, low-cost rapid charging facilities fed from existing standard local power supply cables. Compatible with all OLE-powered trains, the novel design enables the removal of diesel passenger train operation on non-electrified routes across the UK, while minimising land requirements and modifications required to existing station structures.
My Thoughts And Conclusion
Consider.
- The solution works with all 25 KVAC trains.
- It looks like it is a compact overhead electrification system, which might have originally been designed for a European tram or German S-Bahn system.
- It is claimed to be low-cost.
- Siemens were not asking for a lot of money.
- ROSCO, TOCs and Network Rail are all involved, which must be good.
It looks to me, that someone at Siemens has raided the parts bin and found some small, low-cost overhead electrification, that can be installed in the UK gauge and powered by a fairly standard mains supply.
It strikes me, that this system would be ideal to install in a station like Marylebone, if services to the station were to be run by battery-electric trains.
A Rapidly Deployable Rail Stress Sensor For Next Generation Freight Monitoring
This project was one of the winners in the First Of A Kind 2022 competition run by Innovate UK.
In this document, this is said about the project.
Project No: 10039559
Project title: A Rapidly Deployable Rail Stress Sensor For Next Generation Freight Monitoring
Lead organisation: PEAK TO PEAK MEASUREMENT SOLUTIONS LTD.
Project grant: £263,725
Public description: As UK rail freight growth increases, a detailed live understanding of the network condition is
essential and is driving the need for industry digitalisation in the form of real-time and in-situ condition monitoring.
This is also a key enabler of automated networks and the adoption of autonomous vehicles.
In the UK many of the existing wayside rail measurement technologies (e.g. Weigh-in-Motion[WiM] and Wheel Impact Load Detector [WILD]) are expensive, time consuming to install, and permanent.
Thus, the adoption of measurement technologies for improving service offerings is becoming increasingly important. Some proposed data streams are unmeasurable using commercially available technologies; other smaller rail sensors on the market only offer very basic measurements (such as vibration and temperature). Some can be achieved through strain gauging, weighbridges or manual inspection. However, Peak to Peak Measurement Solutions (PktoPk)’s solution is more robust, has longer term stability, is rapidly deployable, offers higher measurement frequency and is significantly cheaper/faster to deploy than any of the competing technologies. It builds on similar systems PktoPk have deployed to non-competing industries such as automotive, large marine diesel, and injection moulding.
PktoPk proposes a novel technology to take key measurements using an ultrasonic array transducer mounted in a robust clamp that can be rapidly fixed under a rail of any gauge. Measurements will be taken in real-time and uploaded to a cloud platform. This solution is fast, portable and excellent value for money whilst providing tangible, reliable and cost-saving data.
The system benefits to asset owners include; reducing possession duration, reducing inspection/maintenance downtime and providing rail operators with easy access to all the data streams listed below.
- Dynamic lateral and vertical force (L/V)
- Wheel-rail contact position and shape
- Wheel-rail interfacial stiffness
- Axle load/weight (ALM)
- Additional ‘standard’ measurements (temperature/noise/vibration)
The project will utilise PktoPk’s close relationship with University of Sheffield, where the IP and right to operate is also shared, and will work with other local partners to create a demonstration of their novel technology to key rail stakeholders in a live rail environment.
This event will also be broadcast with some international stakeholders who have already expressed their excitement about the demonstration.

Automating Freight Access Right Management And Spot Bidding Using Novel And Modern Software To Drive Modal Shift From Road To Rail
This project was one of the winners in the First Of A Kind 2022 competition run by Innovate UK.
In this document, this is said about the project.
Project No: 10039135
Project title: Automating Freight Access Right Management And Spot Bidding Using Novel And Modern Software To Drive Modal Shift From Road To Rail
Lead organisation: HACK PARTNERS LTD.
Project grant: ££322,420
Public description: Automating today’s manual processes associated with access right management and spot bidding and wrapping these digital processes in an intuitive, integrated, modern, bespoke and scalable user system. The benefits of this innovation are not only cost efficiency but also enabling a much better experience to freight customers to drive modal shift.
Transforming High-Speed Rail Logistics
This project was one of the winners in the First Of A Kind 2022 competition run by Innovate UK.
In this document, this is said about the project.
Project No: 10038447
Project title: Transforming High-Speed Rail Logistics
Lead organisation: VARAMIS LTD
Project grant: £396,467
Public description:
Our project is to transform high-speed rail logistics combining a repurposed all electric passenger unit and bespoke consignment device technology to support the conveyance of parcels. This technology, offered alongside a new approach to using space at stations to create easily accessible city-centre distribution hubs, will enable the operation of a new high-speed non-letters parcels service.
The project meets the competitions challenge and scope through: Development and application of new technologies and approaches to rail, innovative reuse of existing rail assets (such as passenger rolling stock converted for light freight), repurposing of space at station hubs (which has been released due to changing passenger demand) and engagement with new to rail logistics operators to develop and grow new high-speed rail freight services.
Furthermore, the project is in support of permanent modal shift from road to rail, delivering rail freight growth, meeting future customer needs, and realising significant emissions reductions which supports the UK’s low emissions target of a 68% reduction by 2030, compared to 1990 levels through modal diversion from road.
My Thoughts And Conclusions
Levelling Up Freight
This project was one of the winners in the First Of A Kind 2022 competition run by Innovate UK.
In this document, this is said about the project.
Project No: 10037240
Project title: Levelling Up Freight
Lead organisation: 3SQUARED LTD.
Project grant: £393,271
Public description:
Background
Rail freight is vital to Britain. It contributes almost £2.5bn to the economy and plays a big part in reducing congestion and emissions. Rail is more environmentally friendly than road, with every tonne of freight transported by rail producing 76% less emissions compared to road (RDG “Levelling Up Britain” 2021). The green benefits of rail freight are being driven heavily by the DfT with incentive schemes such as Modal Shift Revenue Support (MSRS) – a £20m grant, which
freight carriers can bid for a share of to support modal shift to rail.
Despite widescale use of MSRS, finding new freight routes for additional trains is challenging because:
- Road haulage is seen as easier and more accessible than rail freight, especially at short
notice, for short journeys and for single containers. - Highways are less regulated with no significant barriers to commercial participation, and
therefore are free to use the latest technologies to develop and evolve solutions at a faster
pace. - Railway planning systems and processes limit the availability and visibility of freight paths
(slots in the timetable which can accept a freight train) resulting in under-utilisation of
network capacity.
Our innovative freight planning solution (PathPlanner) will make the use of rail for freight as
accessible and easy to use as the road network. PathPlanner is specifically designed to overcome
the current operational challenges and blockers that make moving to rail prohibitive.
Proof-of-Concept Demonstration
In 2021, NR completed a £17m upgrade around Southampton to enable longer trains in/out of the docks. Completing April 2023, Solent Stevedores is investing c.£3m to strengthen their capability to receive and dispatch longer and more trains – from 9 to 16 per day.
However, NR’s business case did not include any understanding of capacity in/out of the port, so
Solent Stevedores is currently unsighted as to how, or if, they can find the additional paths.
There are significant gains to be made if they can; 7 extra trains equate to:
- £12.6m additional revenue p.a.
- A reduction of 55,000 HGVs.
- A reduction of carbon by 1,165 tonnes.
Our project will demonstrate a Proof-of-Concept solution at Southampton Docks that will facilitate
Solent Stevedores, and Eddie Stobart Logistics (ESL) – 2 off our project partners – to find additional
freight paths and transfer containers from HGVs to trains.
My Thoughts And Conclusions
As I programmed scheduling and resource allocation systems for forty years, I am probably one of the most experienced programmers at writing this type of system.
That experience suggests that their objectives are possible.
Decarbonising Auxiliary Load In Freight Today
This project was one of the winners in the First Of A Kind 2022 competition run by Innovate UK.
In this document, this is said about the project.
Project No: 10039629
Project title: Decarbonising Auxiliary Load In Freight Today
Lead organisation: G-VOLUTION LTD
Project grant: £378,514
Public description: Freight locomotives have auxiliary electric power requirements which account for up to 10-15% of the total power demand, covering engine and traction motor cooling, safety and signalling systems and locomotive control systems.
These loads are currently serviced by an alternator on ubiquitous diesel ICE powertrains. This demand is persistent, requiring the diesel ICEs to remain powered up/idling during the significant periods of dwell time faced by freight services. Up to 20% of freight locomotive fuel consumption and emissions, from CO2 and particulates, therefore arise from non-traction aspects.
Whilst extreme traction requirements for freight operations restricts adoption of full decarbonised powertrains – unless compromises for traction power or range are made – no existing rail technology targets the significant auxiliary power requirements.
In response, G-volution have engaged a team cutting across the full UK supply chain to realise and integrate a first-of-a-kind system for on-board auxiliary power on freight locomotives, based on high energy-density fuel cells and a carbon neutral bio-LPG fuel system.
Whilst initially representing the lowest cost/technical barrier route to catalyse significant CO2, exhaust emission and diesel fuel savings in freight, this approach has potential to also substitute traction power in the long term, and supports the transition to green hydrogen as a rail transport fuel.
Through a live demonstration with a UK freight operator, the project will therefore prove that high efficiency fuel cells, which are able to use a range of cleaner, greener, cheaper zero net carbon renewable fuels, can work in the rail environment and also stimulate significant commercial benefits for all operators, via reduced fuel costs and future environmental levies.
My Thoughts And Conclusions
Note that another G-volution project is described in Grand Central DMU To Be Used For Dual-Fuel Trial.
I also suspect, this auxiliary power unit could have other applications.
What Is A Freight Skate?
The Freight Skate was one of the winners in the First Of A Kind 2022 competition run by Innovate UK.
The Description In The First Of A Kind 2022 Winners Document
In this document, this is said.
Project No: 10039606
Project title: “Freight Skate” a self-powered freight bogie and platform
Lead organisation: TDI (EUROPE) LIMITED
Project grant: £400,000
Public description: Governments have recognised that the continued dependence on the motor/freight vehicles is unsustainable and that modal shift to low and zero-carbon public transport solutions, both for passengers and freight, is essential if legislative commitments to Net Zero are to be met.
The Freight Skate provides a sustainable, low cost, reliable and high-quality rail freight experience which will drive down emissions and increase profits to freight companies and assist in bringing about the much-needed modal shift from road to train. To achieve this objective, it required us to use different ways of thinking across every aspect of the programme – design, supply, build and system implementation. This approach has yielded the desired results.
The skate chassis was originally designed with steering axles for passenger trains. It is a unique and tested design which we believe lends itself to operating as an independent 4-wheel unit that can be virtually coupled to form a platform for 10′, 20′,30′ or 40′ containers. The study would also allow us to optimise loading for 9’6″ HC units; Three units could also be used to carry 2 x 40′ containers. An individual unit would carry a 10′ container.
TDI plans to commercialise the Freight Skate vehicle over the next 3 years, with the product entering freight terminal service in 2025.
My Thoughts And Conclusions
If you search the Internet for “Freight Skate” you find nothing, but I think the concept is a development of the TruckTrain, which I wrote about in The TruckTrain, as both concepts are from Coventry.
I really liked the TruckTrain concept, when I saw it earlier this year.

Cambridgeshire Company’s Self-Charging Trains Project Wins Government Funds
The title of this post, is the same as that of this article on the BBC.
These four paragraphs outline what the company is developing and how they received government funding.
Echion Technologies, based in Sawston near Cambridge, is creating train batteries that can charge from overheard wires, the Department for Transport said.
The trains would be able to use the batteries on unelectrified track.
The project was among the winners of the government’s First of a Kind competition.
The competition aims to award funding to projects that could transform the future of transport.
I have a few thoughts.
The Description In The First Of A Kind 2022 Winners Document
In this document, this is said.
Project No: 10039100
Project title: UBER – Ultra-high power Battery for low Emission Rail
Lead organisation: ECHION TECHNOLOGIES LTD
Project grant: £59,917
Public description: Project UBER (Ultra-high power Battery for low Emission Rail), aims to demonstrate for the first time, Echion’s XNO(tm) battery chemistry as the preferred battery technology for certain classes of battery electric trains. It targets Theme 1 of this competition.
Specifically, UBER aims to demonstrate the suitability of XNO(tm) for passenger trains that can be powered by the AC overhead electrification and charge a battery from the overhead wire (or another form of ‘standard’ trackside power — e.g. 3rd rail), to then run in battery-only mode on unelectrified section of a route. An example of such a train is the Revolution Very Light Rail (Revolution VLR) developed by Transport Design International (TDI), who is a partner in UBER.
Applying The Echion Technologies Batteries To Electric Trains
Consider.
- The BBC article is accompanied by a picture of a Class 717 train, which like the Class 700 train is dual voltage.
- Southeastern have thirty similar Class 707 trains, which are third-rail, although according to Wikipedia, were tested as dual-voltage trains.
- Most modern trains, like these Desiro City units made by Siemens, have a mix of motored and trailer cars, with one or more pantograph cars between the two driver cars.
- Because power is needed in all cars, there will be an electrical bus from one end of the train to distribute power.
- All trains in the family appear to have at least one trailer car, which will also be connected to the electrical bus.
With a family of trains like the Desiro City, Alstom’s Aventra, CAF’s Civity, Hitachi’s AT-200 or AT-300 or Stadler’s FLIRTs, train manufacturers assemble various cars, interiors and electrical gubbins together, to get the train performance and capability.
I would expect that the battery would be placed, where there is space and the most likely place is under the trailer car.
In some ways, it would work like the battery in a laptop computer, where operation is as follows.
- If there is external power, the computer runs on that power and the battery is also charged, if it is not fully-charged.
- If there is no external power, the computer runs on battery power, until the battery goes flat.
With a battery-electric train, operation is similar, with an important addition.
- If there is external power, the train runs on that power and the battery is also charged, if it is not fully-charged.
- If there is no external power, the train runs on battery power, until the battery goes flat.
- Desiro City and many other electric trains have regenerative braking and under braking, the electricity generated is is stored in the battery, if it is not fully-charged.
It could be considered by some, that regenerative braking is self-charging. But unfortunately, regenerative braking doesn’t recover all energy during braking. But it can be up to 70-80 % efficient.
Connecting The Echion Technologies Battery To The Train
The battery will have to be connected to the electrical bus, that runs the full length of the train.
As a Control Engineer, I suspect there will be a sophisticated control system, that will switch the battery between various modes and control the pantograph and third-rail shoes.
Perhaps, Echion Technologies have developed an all-purpose controller that could fit all trains?
