  From an engineering point of view, a bus has two main components : the body or coachwork and chassis (together with the engine and the transmission) on which the body is built. Both were standardized as far as possible. In the period upto 1960 different manufacturers built varying bus-bodies. Some bus-bodies were of composite type and some were built of steel and aluminium. These variations proved troublesome and costly in maintenance. A decision to have complete metal bodies was taken and brought into effect from 1962. Another early step was to standarize the various fitments on bus-bodies. In 1967, with a view to standardizing bus construction, buses were classified into three types. Type A comprised single deckers, steel-built throughout. Type B comprised double - deckers, also steel-built throughout. Type C included both single deckers and double-deckers and used both steel and aluminium in their construction. Manufacturers build these types of buses in conformity with special designs prepared by the Transportation Engineering Department. The demands of city transport are different in some respects from those of other transport. In the city gear-changes are far more frequent and brakes must be extremely efficient. A large diesel tank is required; medium horse-power is adequate for the engine. Transportation Engineering takes all these requirements into account in designing a chassis to suit the special needs of city traffic. Efforts are being made to improve the bus-bodies and make them better looking. |
