Network Rail has granted new Class 99 locomotives being introduced by GB Railfreight (GBRf) an Interim Network Rail Statement of Compatibility (NRSC).

This is an important requirement for Class 99 locomotives to operate across Britain’s railway network. Although being an interim statement, it marks an important step towards full certification, which GBRf and Network Rail will continue working towards.

The first six Class 99s have now entered GBRf’s fleet, which will allow an increase in driver training before the locomotives enter commercial service this summer.

Built by Stadler specifically for the UK market, Class 99s are bi-mode locomotives, which can be powered from overhead electric lines or a Stage V-compliant diesel engine on non-electrified routes.

Their bi-mode capability makes them suitable for operating throughout the UK, while also reducing emissions. When operating on electric power, the Class 99s emit lower emissions and offer reduced fuel consumption compared with traditional diesel-only locomotives. They also have a greater haulage capability and improved reliability, and by eliminating the need to change traction between electrified and non-electrified lines, they provide a greater network flexibility.

The first six out of a total of 30 Class 99s on order have been accepted into GBRf’s fleet, and numbered 99001 to 99006. Number 99007 will soon begin trials for fault-free running, and numbers 99008 and 99009 are being shipped to the UK later this month. GB Railfreight staff are using Apple Vision Pro for remote learning to train them on the cab layout before they operate real locomotives.

”The granting of the Statement of Compatibility for our Class 99 locomotives is a significant moment for GB Railfreight and the wider sector. I would like to thank the teams at Network Rail and GB Railfreight who have worked tirelessly to reach this point. Achieving compatibility on Britain’s complex railway infrastructure is no small task, and this has been a collaborative effort throughout. The Class 99 represents the future of rail freight, combining improved performance with clear sustainability benefits. With this approval secured, we are now focused on bringing the locomotives into service.”
