A FRAMEWORK agreement to build 30 tri-mode locomotives has been signed by Stadler and Rail Operations (UK) Ltd. 

The new mixed-traffic Bo-Bo machines will be based on Stadler’s established Class 68 and Class 88 fleets, but will be able to operate on 25kV or a CATERPILLAR C32 diesel engine.

The diesels have a nominal power of 900 kW and meet EU 97/68 Stage V emission requirements. Each will be backed up by two Lithium Titanate Oxide traction battery packs, which will provide an additional 400kW. The batteries will also be usable on their own for ‘last mile’ shunting moves.

The fleet will be designed and built in Spain, and the first 10 Class 93s are due to be delivered in early 2023.

The value of the contract is not being disclosed.

Rail Operations CEO Karl Watts said: ‘The rail industry has acted very positively in understanding its role in reducing carbon emissions and improving inner city air quality. The class 93 fleet with its array of green credentials, will allow us to lead the way in supporting the rail industry deliver its decarbonisation targets. Furthermore, with its impressive state-of-the-art specification, the Class 93 also allows us to develop new markets and modernise many aspects of UK train operations.’
