UK: Stadler and Rail Operations (UK) Ltd have signed a framework agreement for the supply of 30 Class 93 trimode locomotives, with an initial batch of 10 scheduled for delivery in early 2023.

The Bo-Bo locomotives will be based on the Class 68 UKLight diesel and Class 88 UKDual electro-diesel locos supplied to Direct Rail Services, but will have a higher maximum speed of 180 km/h rather than 160 km/h.

The locomotives will have a rating of 4 MW when running under 25 kV 50 Hz electrification. They will also have a 900 kW Caterpillar C32 diesel engine meeting EU 97/68 Stage V emission regulations for use on non-electrified lines, and two lithium titanate oxide traction battery packs to provide 400 kW of extra power to supplement the engine or for emissions-free last mile shunting.
