GB Railfreight (GBRf) has reached two significant milestones in the introduction of its new Class 99 locomotive fleet, marking an important step towards their entry into commercial service this summer.
Network Rail has granted the Class 99 fleet an Interim Network Rail Statement of Compatibility (NRSC), allowing the locomotives to operate across Britain’s rail network. GBRf and Network Rail will continue working together towards full certification. In addition, GBRf has formally accepted the first six Class 99s into its fleet, enabling driver training to scale up ahead of commercial operations beginning later in the year.
Manufactured by Stadler and designed specifically for the UK market, the Class 99 is a bi-mode locomotive capable of running on overhead electric power where available, supported by a Stage V-compliant diesel engine for non-electrified routes. This combination provides the flexibility required for nationwide freight operations while reducing emissions compared with traditional diesel-only locomotives.
By maximising electric operation, the Class 99 delivers lower fuel consumption, enhanced haulage capability, improved reliability and greater network flexibility, removing the need to change traction between routes.
The fleet is expected to play a key role in the decarbonisation of rail freight, while maintaining the resilience and reach that GBRf’s customers require across the UK.
John Smith OBE, Chief Executive Officer of GB Railfreight, said:
“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.”
