The gameplay in this Add-on simulates the movement of radioactive nuclear material up and down two stretches of the West Coast Main Line.

The role of these trains is simple; safely carry nuclear flasks between power stations and processing centres across the UK. This important task has made them a popular and rare catch for enthusiasts, and despite the reduction in nuclear power plants since the millennium, the trains are still seen in use to this day.

The English Electric Type 1 / Class 20 locomotive, known to many as 'Choppers' (because of the distinctive engine sounds), first appeared in Train Sim World as a Loco Add-on for the Tees Valley Line, set in the early 1990s. Cargo Line Volume 5 introduces a new contemporary version, circa 2000.

Due to the volatile nature of their cargo, Nuclear trains are often operated with multiple locomotives at once. The modernised Class 20/3 was one such type of locomotive assigned to the role. Bookending the wagons between locos protects them against any direct impact, and additional diesel engines added contingency in case of a failure. Wherever possible, the Nuclear train must remain moving and is given high priority across the network.

Sandwiched between a pair of Class 20s is the FNA-D Nuclear Flask Wagon, new to Train Sim World.

Plus seasonal layered services for Riviera Line (other Add-ons required).

Please note that for PlayStation 4 and Xbox One, the spread of other trains running around has been reduced to provide acceptable performance. This reduction does not apply to PC, Xbox S/X or PlayStation 5 versions.
