“Porterbrook welcomes Jo Johnson’s call for the railway to provide a vision on how to decarbonise rolling stock.

“Porterbrook is already actively engaged with its customers, the railway supply chain and other sectors to identify alternative power sources for trains operating on non-electrified routes.

"Our team of highly experienced rolling stock engineers and asset managers look forward to playing a key role in helping the industry to safely and effectively deploy alternative fuel sources on self-powered trains by 2040.”
