The Train Sim World BR Class 20 'Chopper' Loco Add-On brings the BR Class 20 diesel locomotive to Train Sim World for duties on the Tees Valley Line. The add-on includes a BR Railfreight-liveried locomotive and a PGA hopper wagon.

The Class 20

The locomotive began as the English Electric Type 1, developed in the 1950s as British Railways’ first major step towards dieselisation. After trials and failures, the 1000 hp (746 kW) Type 1 proved promising. A total of 228 were built between 1957 and 1968, taking over from steam locomotives of similar power and mainly hauling light, mixed-freight traffic in the Midlands and Scotland.

The Type 1 has a single cab at the rear, with controls facing in either direction. The diesel engine and equipment sit in front of the cab, giving the locomotive a tank-engine-like appearance. The first 127 examples also had headcode discs at both ends. Because forward visibility was limited when travelling nose first, Type 1s were often coupled nose to nose; this improved the view of the track and doubled their power for heavier trains.

Under the TOPS classification system, the Type 1 became the BR Class 20. Its engines’ helicopter-like sound under load gave it the nickname “Chopper”. Class 20s remain in operational use, and 20 examples have survived in preservation, where they are a regular sight on heritage railways.

Scenarios and services

The add-on includes three scenarios and interactive training modules for the Tees Valley Line. The Class 20 can also run in Timetable Mode on that line, with additional scheduled services that increase traffic on the route, and in Timetable Mode on the West Somerset Railway.

Locomotive features

The locomotive features detailed driving cabs, performance and handling based on the real locomotive, and sounds recorded from real examples. Its vehicle dynamics use Dovetail Games’ SimuGraph engine alongside Unreal Engine 4.
