The AEC Renown was a front-engined low-height double-decker bus chassis manufactured by AEC. It superseded the AEC Bridgemaster around 1962. [1]
The low-height double-decker AEC Bridgemaster was nearing the end of its production when AEC launched the Renown as its successor around 1962, not long before the acquisition of AEC by Leyland. The main difference between the Renown and its predecessor was the chassis design, the Renown was designed as a complete chassis, rather than integral construction adopted by the Bridgemaster, thus the Renown could be suited to different body designs. [3] The engine was the AEC AV590, as used in the Bridgemaster, which had a displacement of 590 in3 (9.7 L) and developed 128 bhp (95 kW) at 1,800 rpm. The transmission could either be the AEC "Monocontrol" semi-automatic three-speed epicyclic gearbox, or a clutch and four-speed synchromesh gearbox. Two prototypes were built in 1962, one for each transmission option; the monocontrol example (model 3B2RA) was tried out by London Transport, and the synchromesh example (model 3B3RA) was initially exhibited at the Commercial Motor Show, and then used by AEC as a demonstrator. In the model codes, the initial 3B indicated a Renown (the Bridgemaster having been B or 2B); the next figure showed the number of pedals and thus the type of transmission – the Monocontrol option had no clutch pedal; the R denoted right-hand drive; and the A denoted air brakes. [4]
The design, like the Bristol Lodekka and the Dennis Loline meant this double-decker could travel under low height bridges, whilst maintaining near-full-height standing room.
Bodywork was constructed by a variety of coachbuilders, primarily Park Royal Vehicles which built 130, but also included: East Lancs (33); Northern Counties (39); and Weymann (40). Most had the entrances situated just behind the front axle, but fourteen of those built by East Lancs had rear entrances. Major customers included City of Oxford Motor Services (43); East Yorkshire Motor Services (34); North Western Road Car Company (33); Nottingham City Transport (42); and Western Welsh (28). Virtually all customers specified the synchromesh transmission – only five (including one of the prototypes) were built with the Monocontrol transmission. [4]
After Leyland acquired a 25% stake of Bristol Commercial Vehicles and Eastern Coach Works in late 1965, Leyland had three different front-engined low-height double-deck designs: AEC Renown, Bristol Lodekka and Albion Lowlander. Leyland quickly decided to cease taking orders for the Renown and Lowlander. The last AEC Renown was delivered in 1967, [3] with a total of 251 buses built.
Central Scottish Omnibuses Ltd was a bus operating subsidiary of the Scottish Transport Group formed in June 1985 from Central SMT, and operated until July 1989 when it was merged with Kelvin Scottish to form Kelvin Central Buses.
The Dennis Dominator was Dennis's first rear-engined double-decker bus chassis, it was launched in 1977.
Seddon Atkinson Vehicles Limited, was a manufacturer of large goods vehicles based in Oldham, Greater Manchester, England, was formed after the acquisition in 1970 of Atkinson Vehicles Limited of Preston by Seddon Diesel Vehicles Limited of Oldham. In 1974, the firm was acquired by International Harvester, which sold it in March 1984 to the Spanish group Enasa which made it a subsidiary of Pegaso. In 1990, it became part of Iveco which used the brand for various types of specialised vehicles in the United Kingdom. The range of models produced included EuroMover, Pacer and Strato, which are aimed at refuse collection, recycling and construction operators.
Albion Motors was a Scottish automobile and commercial vehicle manufacturer.
A preselector gearbox is a type of manual transmission mostly used on passenger cars and racing cars in the 1930s, in buses from 1940-1960 and in armoured vehicles from the 1930s to the 1970s. The defining characteristic of a preselector gearbox is that the gear shift lever allowed the driver to "pre-select" the next gear, usually with the transmission remaining in the current gear until the driver pressed the "gear change pedal" at the desired time.
The Leyland Titan was a forward-control chassis with a front-mounted engine designed to carry double-decker bus bodywork. It was built mainly for the United Kingdom market between 1927 and 1942, and between 1945 and 1969.
The Leyland Atlantean is a predominantly double-decker bus chassis manufactured by Leyland Motors between 1958 and 1986. Only 17 Atlantean chassis were bodied as single deck from new.
The Bristol VR was a rear-engined double-decker bus chassis which was manufactured by Bristol Commercial Vehicles as a competitor to the Leyland Atlantean and Daimler Fleetline.
The Bristol Lodekka was a half-cab low-height step-free double-decker bus built by Bristol Commercial Vehicles in England. It was the first production bus design to have no step up from the passenger entrance throughout the lower deck; although Gilford and Leyland Motors had developed low floor city buses in the 1930s, these did not enter production.
The Leyland Leopard was a mid-engined single-decker bus and single-decker coach chassis manufactured by Leyland between 1959 and 1982.
Charles H Roe was a Yorkshire coachbuilding company. It was for most of its life based at Crossgates Carriage Works, in Leeds.
The AEC Reliance was a mid-underfloor mounted engined single-decker bus and coach chassis manufactured by AEC between 1953 and 1979. The name had previously been used between 1928 and 1931 for another single-decker bus chassis.
A lowbridge double-deck bus is a double-decker bus that has an asymmetric interior layout, enabling the overall height of the vehicle to be reduced compared to that of a conventional double-decker bus. The upper-deck gangway is offset to one side of the vehicle, normally the offside, and is sunken into the lower-deck passenger saloon. Low railway bridges and overpasses are the main reason that a reduced height is desired.
The Dennis Loline was a low-height double-decker bus manufactured by Dennis between 1958 and 1966.
The Leyland Tiger Cub was a lightweight underfloor-engined chassis manufactured by Leyland between 1952 and 1970.
The Daimler Roadliner was a single-decker bus and coach chassis built by Daimler between 1962 and 1972. Notoriously unreliable, it topped the 1993 poll by readers of Classic Bus as the worst bus type ever, beating the Guy Wulfrunian into second place. It was very technologically advanced, offering step-free access some 20 years before other buses; as a coach, it was felt by industry commentators to be in advance of contemporary UK designs.
The Daimler Freeline was an underfloor-engined bus chassis built by Daimler between 1951 and 1964. It was a very poor seller in the UK market for an underfloor-engined bus and coach chassis, but became a substantial export success.
The Leyland Tiger was a heavyweight half-cab single-decker bus and coach chassis built by Leyland Motors between 1927 and 1968, except the period of World War II.
The Albion Lowlander was a Scottish-built low-height double-decker bus.
The AEC Bridgemaster was a front-engined low-height double-decker bus chassis manufactured by AEC.
