Train Simulator: BR Class 421 ‘4CIG’ Loco

Once a very familiar sight across the railways of southern England, the 4CIG electric multiple unit is a classic example of the heritage ‘slam-door’ passenger trains which once formed the backbone of southern passenger services.

Extensive 3rd-rail electrification of the Southern Region led to the widespread adoption of these practical EMUs, and the 4CIG (British Rail Class 421) was initially introduced on the London-Brighton Line before being pressed into service on the Portsmouth Direct Line between London Waterloo and Portsmouth Harbour.
