NATIONAL SERVICE: THE DEVELOPMENT OF THE LEYLAND NATIONAL BUS

The history of the successful Leyland National City Bus is traced from its first introduction in 1972 to the present time when over 6000 have been produced. The design for a standardised single-deck integrally-constructed city bus met considerable opposition. The rear-engined design enabled a low floor level to be utilised and a new turbocharged diesel engine was incorporated. Passenger comfort was improved by the use of a rolling diaphragm air suspension, and interior temperature was controlled by an automatic unit mounted on the roof at the rear. Ergonomics were used to produce the cab layout and an energy absorbing structure was used. Although several different configurations of bus are available, as many common components as possible are used. Some initial problems in operating the buses could possibly have been avoided by in-service proving. Minor improvements have been incorporated all the time up to the first major alteration in 1976 and an economy version introduced in 1978. /TRRL/
