Heritage railway joins forces to build a locomotive for the future
The Severn Valley Railway has teamed up with the University of Birmingham and local start-up company, Vanguard Sustainable Transport Solutions, to work on a ground-breaking scheme. The Harrier HydroShunter project will see the UK’s first-ever conversion of a diesel locomotive to run on hydrogen power.
Work is already underway at the heritage railway’s diesel depot at Kidderminster, where a team of young volunteers are stripping down the donor vehicle. They’re removing the existing diesel engine and generators and overhauling other components, as they prepare Class 08 shunter No 08635 to receive its new power system.
Vanguard Sustainable Transport Solutions is designing the hydrogen-battery hybrid traction system. This will be made up of hydrogen cylinders, a hydrogen fuel cell stack and a hybrid battery.
The cylinders will store hydrogen as a pressurised gas, which will be fed to the fuel cell stack via a regulator. In the fuel cell stack, hydrogen will be combined with oxygen from the air, to produce electricity to power the locomotive. Meanwhile, the battery will store energy to provide additional power for when it’s needed.
The equipment will be mounted on a sub-frame, fitted to the existing engine mountings. It will supply the existing traction motors of the Class 08, which will keep its existing controls.
Mike Ball, the Severn Valley Railway’s vice chairman, has been closely involved with the project from its inception:
“We were delighted when the University of Birmingham asked us to get involved in this project. As a heritage railway, we’re actively looking for ways to reduce our carbon footprint, and having a hydrogen-powered shunter will play a key part in that plan.
“The current preparation stage for the Harrier shunter is providing an excellent opportunity for some of our younger volunteers to put their skills to good use. The group working on the 08 are all still in their teens, and their ability to plan and implement this task has been nothing short of amazing. They’re the volunteers of the future, working on a locomotive for the future.”
Alexander Burrows, director at the University of Birmingham’s Centre for Railway Research and Education (BCRRE), added:
“Our team at the University of Birmingham are pioneering the designs and opportunities to bring hydrogen technology to the UK railway. Following the success of our HydroFLEX project with Porterbrook that delivered the UK’s first mainline approved hydrogen train, we are thrilled to be working with the Severn Valley Railway and Vanguard to roll out the Harrier HydroShunter.
“This is another fantastic project where BCRRE has partnered with a leading heritage railway and an innovative local start-up business to pioneer our research in a real world industrial application.”
