Leyland National - Design

Design

The Leyland National was built with integral, modular construction and a rear engine. All components were designed for ease of construction and replacement. Until 1978, it was always built with a distinctive roof mounted pod at the rear, housing the heating equipment, which consequently blew warm air out at roof level. At first the pod was almost the length of a bay and appeared designed to give a Trans-Atlantic feel. In 1976 a new shorter version of the roof pod was introduced along with the battery being relocated to the front under the cab. The Leyland National was available in two lengths, 10.3m and 11.3m. It was easy to spot the shorter one because of its squarer windows.

The Leyland National was a simple design: all parts could be replaced. Some operators, like London Transport, bought dual door models, and then later configured some of them to single door. This was helped by the design of the body, and the fact that parts were inter-changeable.

The earlier vehicles were only available in three colours - National Bus red, National Bus Green and White. At London Transport insistence, London bus red was added to the colour card, and their fleet eventually amounted to over 500 examples acquired between 1973 and 1980.

In 1978, Leyland brought out a simplified model (10351B/1R) with a revised interior that had minimal lighting and without the rear roof-mounted heating unit in previous models. Heating was under the seats, and was basic but effective. These vehicles were lighter, and this characteristic and the lower cost helped make extra sales. London Country bought quite a number of these, which other operators snapped up when London Country was broken up.

The National 2 was introduced in 1979. It differed from its predecessor mainly by having a wider choice of engines, along with a new nose moulding giving it a more bulbous look and a grille to cool the new front-mounted radiator, and a revised rear end with new lights and different engine door.
