AEC S-type 401-404 range

The AEC 401 model chassis, produced for London General Omnibus Co, as its S type bus, first made its appearance in December 1920. It has a wheelbase of 14ft 1in and was designed to carry double deck open top bodywork type with seating for 54 passengers. Fitted with solid tyres it is powered by an AEC 4-cylinder petrol engine of 35hp rating, and has a multiple clutch and 3-speed gearbox.

In 1924 the S type appeared carrying single-deck bodywork the chassis being the same as that used for double-deckers. All these single-deckers were later converted to pneumatic tyres, as indeed were a small number of double-deckers.

The 401-404 series finally ceased to be produced in 1925 by which time a total of 1,066 had been built.
