British Railways Class 488 EMU (Gatwick Express)

Class 488 emus* (*they're actually unpowered trailer sets, designed to work in a push-pull configuration with a Class 73 at one end and a Class 489 at the other). These 2-car and 3-car sets were converted from Mark 2 coaches by installing permanent couplings and moving the outer-end brake pipe connections up to match the height of those on a class 73 locomotive. These sets were used on Gatwick Express services prior to the arrival of the Class 460s and later Class 442s.
