Rail Operations (UK) has reached a framework agreement with Swiss manufacturer Stadler for the delivery of 30 Class 93 tri-mode locomotives.
The new locomotives will help in achieving the goals of rail decarbonisation in the UK.
The first batch encompassing ten locomotives will be delivered in early 2023.
Rail Operations said that the Class 93 tri-mode locomotives will cut down CO2 emissions for rail freight and potential passenger transport services.
Class 93 Bo’Bo’ mixed-traffic locomotive is an evolution of Stadler’s Class 68 and Class 88 locomotives.
In comparison with the previous version, these locomotives can reach speeds of 110mph.
The company noted that Stadler’s first tri-mode train has three different sources of power.
With a power of 4,000kW, these trains can run on 25kV AC overhead lines in electric mode.
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 93s also allow us to develop new markets and modernise many aspects of UK train operations.”
The trains can also operate over non-electrified lines as they are equipped with a CATERPILLAR C32 engine and Lithium Titanate Oxide (LTO) traction battery packs.
The diesel engine meets EU 97/68 Stage V emission requirements with a nominal power of 900kW.
The two LTO battery packs supplement the engine by providing 400kW extra power when the locomotive is operating in diesel/battery hybrid mode, as well as last-mile carbon-free shunting operation.
Stadler Valencia CEO Iñigo Parra said: “The innovative and cost-effective solution will provide environmentally friendly rail transport services, supporting national decarbonisation strategies and promoting a modal shift to rail.”
