The British Rail Class 99 is a class of dual-mode electro-diesel Co-Co locomotives that will haul freight trains on both electrified and non-electrified lines. It is based on the Stadler Euro Dual platform.
Specification
[edit]The 75 mph (120 km/h) locomotive has a maximum tractive effort of "up to" 500 kN (110,000 lbf), and a power rating of 6,170 kW (8,270 hp) in electric mode.[2] These figures exceed those of the diesel-powered British Rail Class 66.
Diesel performance
[edit]The Class 99 locomotive has a 16-cylinder 1,790 kW (2,400 hp) Cummins QSK50 engine installed.[2]
Peter Dearman, an expert in traction electrification,[3] reported in Rail Engineer in early 2023 that the Class 99 may only be able to deliver 1,600 kW (2,100 hp) at the rail in diesel mode.[4] However, this was before the first production locomotive was exhibited at InnoTrans in September 2024.[2]
The chief executive of GBRf, John Smith, reports that the Class 99, despite having a less powerful diesel engine than the Class 66, will outperform the Class 66 at low speeds. The greater tractive effort means that the Class 99 on diesel power can deliver more power at the rail than the 66.[5]
Planned use
[edit]The locomotives are expected to enter service in 2025,[6] and will most likely to be first used for intermodal work on the West Coast and East Coast mainlines.[5]
They will be maintained by Stadler at a new facility in Leicester.[7]
History
[edit]In April 2022, Beacon Rail and GB Railfreight signed an agreement for the supply of 30 locomotives to replace their Class 66 locomotives.[8][9]
The locomotive was formally launched by GBRf in September 2024 at Innotrans 2024.[2] Testing will begin in the UK in May 2025.[2]

Bi-mode locomotives have the flexibility to take power from the wires or diesel fuel. Yet they have limited spaced for an engine due to their electric traction equipment.
