British United Traction, BUT, was a division of Leyland Motors Ltd which produced railway equipment. Leyland flatbed Leyland Motors was a British vehicle manufacturer of lorries and buses. ...

Early British Railways DMUs

BUT produced 11 lightweight diesel multiple unit vehicles for British Railways during the 1950s, numbered 79740-79750. They were of three different types (DMS, DMBS and TS), and could be made up into two- or three-car units. They were not very successful and were withdrawn at an early stage, so never received TOPS classification. DMU, type SA108 of Great Poland Voivodship in PoznaÅ„, Poland German DMU of class 628 A diesel multiple unit (DMU) is a train whose carriages have their own motors powered by a diesel engine. ... Logo of British Rail British Railways (BR), later rebranded as British Rail, ran the British railway system from the nationalisation of the Big Four British railway companies in 1948 until its privatisation in stages between 1994 and 1997. ... The Total Operations Processing System, better known by its initials TOPS, is a computer system for managing the locomotives and rolling stock (railroad cars) owned by a rail system. ...

First Generation DMUs

BUT also built the powertrain for the majority of British Railways' First Generation diesel multiple units. To meet Wikipedias quality standards, this article or section may require cleanup. ...

Engines

Turbo-charged versions of the 11.3 litre and and 15 litre engines were available, boosting the power outputs to 200 bhp and 275 bhp respectively. The turbo-charged versions were not used by British Railways but they were used by Ulster Transport Authority. Air foil bearing-supported turbocharger cutaway made by Mohawk Innovative Technology Inc. ... UTAs logo The Ulster Transport Authority (UTA) ran rail and bus transport in Northern Ireland from 1948 until 1966. ...

Some engines were badged AEC, some Leyland and some Leyland-Albion. Badge engineering is a term that describes the rebadging of one model of car as another. ...

Transmission systems

Most units had Standard Mechanical Transmission. This comprised a fluid coupling, a freewheel and a four-speed epicyclic gearbox. A small number of units had hydraulic transmission, using a torque converter. A fluid coupling is a hydraulic device used for trasmitting mechanical shaft power from a rotating driver to a rotating driven load. ... Freewheel mechanism In mechanical or automotive engineering a freewheel is a device in a transmission that disengages the driveshaft from the driven shaft in the case that the driven shaft would rotate at a higher rpm than the driveshaft. ... Epicyclic gearing is used here to increase output speed. ... A gearbox is an assembly of gears allowing the rotational speed of an input shaft to be changed to a different speed. ... A cut-away model of a torque converter A torque converter is modified form of a hydrodynamic fluid coupling, and like the fluid coupling, is used to transfer rotating power from a prime mover, such as an internal combustion engine or electric motor, to a rotating driven load. ...

Coupling codes

The level of standardisation achieved with BR's first generation DMUs was much higher than it is with modern DMUs. All had side buffers, screw couplings and vacuum brakes and the majority had the standard Blue Square coupling code system for control of engine speed and gear-changing. There were some units with non-standard coupling codes but they were a small minority. The coupling codes were:

Non-BUT engines

Some first generation DMUs were fitted with Rolls-Royce engines. Three types were used: Rolls-Royce Limited was a British car and aero-engine manufacturing company founded by Henry Royce and C.S. Rolls in 1906 and was the result of a partnership formed in 1904. ...

The six cylinder engines usually drove through standard mechanical transmissions but the eight cylinder engines were usually coupled to Twin-disc (Rolls-Royce) torque converters. A supercharger (also known as a blower) is an air compressor used to force more air (and hence more oxygen) into the combustion chamber(s) of an internal combustion engine than can be achieved at ambient atmospheric pressure. ...
