The ‘K’ Type motor bus was a direct descendant of the famous ‘B’ type, born out of the experience gained from, and often compared with, its predecessor. Revolutionary in design, it had many original features. By the end of the First World War most of the ‘B’ types that survived had far exceeded their normal working life. Numbers were low and converted lorries were put into service on many routes to ease the strain. The L.G.O.C., therefore, brought all their design resources to bear and produced a bus which could quickly replenish their fleet and meet the needs of a growing volume of passengers. Built at by AEC, it sat 48, 22 inside and 26 outside. By sitting the driver alongside the engine, and the straight sides with wheel arches gave much more space. Greater space on the rear platform allowed passengers to get on and off simultaneously. Comfortably upholstered inside and electrically lighted, communication between conductor and driver is by an electric bell. The 100 mm bore by 140 mm stroke petrol engine developed 30 hp which, with a worm-driven rear axle of a lower gear, gave a quicker but steadier start. The clutch was a multiple plate Ferodo type. Wider and longer road springs allowed for the extra passengers. Of the 1,100-odd built, only K424 remains. It is maintained in a roadworthy condition and has an annual run to Brighton in the Historic Commercial Vehicle Club’s rally. It can be seen at the London Transport Museum, Acton Depot in Gunnersbury Lane, Acton, West London.
