The 4CIG is a classic ‘slam door’ electric multiple unit that was introduced in 1964, the Class 421 4CIG \(4\-car Corridor Brighton stock\) ran as a 4\-car train comprising a driving trailer, motor coach, unpowered trailer coach and finally a driving trailer\. It is a classic example of the ‘slam door’ EMUs which were once such a familiar sight across the rail networks of southern England\. Extensive 3rd\-rail electrification of the Southern Region led to the widespread adoption of these 90mph EMUs, and the 4CIG \(British Rail Class 421\) was initially introduced on the London\-Brighton Line where its multiple doors enabled rapid turnaround of passengers at the many regular station stops \. The 4CIG units received a facelift in the late 1980s, and continued in mainline passenger service into the 21st Century\!   It is presented in this pack in its London South East livery, known as Jaffa Cake because of the Orange stripe\.   You must own the BR Class 421 '4CIG' Loco Add\-On before you will be able to use this add\-on
