The third-rail Southern Electric network remains one of the most intensively worked suburban systems in the world. The first sections were electrified soon into the 20th century after which its tentacles have grown and expanded from inner suburban to outer suburban areas and now even into Dorset. This book draws exclusively on the work of Geoffrey Kichenside who fortunately recorded the everyday EMU sets and individual vehicles at a time when most enthusiasts were focussing their cameras elsewhere.
