Leyland Royal Tiger
The name Leyland Royal Tiger refers to two different bus models of the British manufacturer Leyland Motors.
Royal Tiger PSU1
The first Royal Tiger was built from 1950 to 1955. The products made in this period chassis received in the name of the abbreviation PSU1. When Royal Tiger it was a chassis with centrally arranged underfloor engine. Was derived from the Leyland Royal Tiger Tiger PS1, the U in the model designation stands for the under-floor mounted diesel engine. The series was initiated by the 1950 the increase in the size limit to approximately 9 m (30 feet) in length. Until the 1980s it was common chassis and bodies for buses were manufactured by different manufacturers. The chassis manufactured by Leyland were therefore completed by body corporate. Accessories like the Ambassador of duple or the Wayfarer I of Harrington were used. These buses were comfortable coaches with 26 seats and a standard sunroof. Motorized these vehicles were equipped with a diesel engine of 9.8 liter displacement ( Ø600 ). Later built cars had a capacity of up to 41 seats, several vehicles were built as a multi- purpose buses for urban and interurban traffic. One of the largest buyers was Southdown coaches, who from 1952 to 1956 Leyland Royal Tiger presented more than 150 bodies of duple, Weymann and Harrington in service. Another manufacturer of bodies was Plaxton.
The lighter chassis of the Leyland Tiger Cub was introduced in 1952. Later evolved into the successful Leyland Leopard, it supplanted the Royal Tiger in a short time almost entirely from the British market. In 1955, a series with a different engine than Leyland Royal Tiger World Master (or simply Leyland Worldmaster ) was again produced for export, but some specimens could also be sold on the domestic market. Some of these were karosseriert as a city bus.
Royal Tiger B50/RT
Between 1982 and 1988 chassis with the name Royal Tiger at Leyland Motors was produced again. It is a chassis with longitudinally under the floor in the rear mounted diesel engine. The series was initially referred to as B50 or B54, later the vehicles the abbreviation given in the designation RT. The Royal Tiger Leyland should secure in the domestic market share against increasingly stronger occurring foreign bus manufacturers like DAF or Scania. The success was, however, within limits, a total of only about 170 vehicles were produced.
All buses of the RTC series were produced as so-called integrated buses. This superstructure and chassis came in contrast to the usual practices of a manufacturer. These buses were given the name Royal Tiger Doyen. The buses B50/B54-Serie were designed conventionally, the chassis were provided by body corporate with superstructures. The majority of buses in this series received superstructures of Leyland's subsidiary Charles H. Roe in Leeds, 15 buses were given the structure of Plaxton Paramount and two buses a buildup of Van Hool. 22 Of the 47 buses of the RT series were given a structure of Plaxton, the rest one by Van Hool. All buses were coaches. Depending on the model 45-53 seats were available, only a few special versions had less seats.
For use diesel engines came from Leyland ( TL11 ) or the Cummins L10.
