The CabSim Project aims to convert upcycled train cabs into accessible, interactive train simulators — designed to be inclusive for wheelchair users and people with limited mobility. Beyond accessibility, CabSim also serves as a safe and welcoming environment for people with autism, allowing them to engage socially or enjoy immersive solo driving therapy in a calm and supportive setting.
This simulator offers users the unique chance to operate a highly authentic “Plastic Pig” driving position, faithfully recreating the original Class 442 cab’s controls, sounds, and atmosphere for a truly immersive experience.
About the Class 442 Wessex Electric
Introduced in 1988, the British Rail Class 442 Wessex Electric units were designed to serve the Southern Region’s main lines, especially the South Western Main Line running between London Waterloo and coastal destinations such as Portsmouth and Weymouth. These trains were constructed at Derby Litchard Lane, creatively combining refurbished Mark 3 coaches with traction equipment salvaged from older 1950s-era Class 432 “4-REP” units. This blend gave rise to the distinctive “Wessex Electric” trains.

Train Simulators for Everyone
CabSim is also built for train enthusiasts eager to experience authentic driving routines and routes. Using Dovetail Games’ Train Sim World software fully integrated within the cab, TC Controllers engineered a sophisticated interface that links the original mechanical controls to digital commands, bringing the best of both worlds together.
At CabSim, we’re here to play, explore, and celebrate the joy of train driving — all within an accessible and caring community.
Saving the Cab
The cab was carefully rescued by The Cab Yard/LMMR in May 2020, thanks to the generous assistance of Raxstar Recycling and Arlington Fleet Services at Eastleigh Works. Removing the cab was a challenging process involving mechanical breaking equipment, with several attempts on other units before successfully extracting the cab from 442405. After being stored for four years, it was selected as the test bed for the innovative CabSim project.
Llanelli and Mynydd Mawr Railway (LMMR)
The LMMR is the home of the CabSim Project which is a heritage railway in Carmarthenshire, Wales, based at the former Cynheidre Colliery site. It features a running track with operational train services, including brake van rides, a collection of historic diesel locomotives and DMUs (including Class 08 and Pacers), and a heritage centre with exhibits and a community café. The site also includes woodland nature trails, developed as part of a conservation project. Open on selected days, the LMMR offers a unique mix of railway history, education, and local nature.
Using the simulator
The simulator will be available to hire, by the hour, day or half day later in 2025. More information will be available in September 2025.
The simulator will be operational at The LMMR open days through out the year for demonstrations runs and on show for taster runs at The Greatest Gathering Derby, Litchurch Lane Derby, 1,2,3, August 2025
