The first two Calss 99 bi-mode locomotives have arrived at the Port of Bristol, marking a pivotal milestone in the process to build and supply 30 bi-mode Co’Co’ locomotives to Beacon Rail and GB Railfreight.
The delivery is part of a contract signed in April 2022 by Beacon and Stadler Rail signed for the supply of 30 bi-mode locomotives to be operated by GB Railfreight.
The 6-axle Class 99s can use existing 25kV overhead line where available combined with their high-power, efficient engine to complete the journey where electrification does not exist.
Their arrival in the UK represents a significant step forward in the project to deliver a 30-strong fleet of state-of-the art vehicles set to transform freight transport. The Class 99 bi-mode locomotives will provide a range of economic and environmental benefits, underscoring Stadler’s green credentials and signalling its commitment to support net zero.
The Calss 99 bi-mode locomotives will soon be taken to Leicester, where they will be maintained by Stadler Rail Services. There they will undergo a rigorous programme of testing and commissioning before entering commercial service by the end of 2025.
The rest of the fleet will begin arriving in the UK in late 2025 and continue throughout 2026.
Based on the proven Eurodual locomotive concept, the Class 99 has been adapted for use on the UK railway network and features a dual drive system. This enables the locomotive to operate in purely electric as well as in diesel-electric mode, allowing it to run on both non-electrified and on electrified lines, potentially replacing diesel-powered locomotives and helping cut carbon emissions on the UK railway.
The Class 99 represents the next generation of locomotive and provides a solution for all freight flows throughout the UK. Able to reach speeds of up to 120 km/h, the Class 99 can run on 25 kV AC electrified lines with a power of 6MW. In addition, they feature a high-power, low-emission Stage V engine for operation on non-electrified lines. The Class 99 boasts a tractive effort of up to 500 kN. The internal environment of the Class 99 will provide optimal visibility, ergonomic desks and seating to promote safety and comfort for operators.
The cab is designed with the driver in mind, and is a safe, modern and comfortable working environment. A centrally positioned seat in combination with the huge front window ensures excellent visibility. State-of-the-art cameras provide direct views of pantographs, shunting zones and the area in front of the locomotive. The two protection systems required on British rail networks, AWS and TPWS have been fitted and ETCS will soon be installed.
