The diamond-shaped, electric-rod pantograph of the Swiss cogwheel locomotive of the Schynige Platte railway in Schynige Platte, built in 1911 Cross-arm pantograph of a Toshiba EMU. A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus [1] to collect power through contact with an ...
Some larger cars in the late '70s and early '80s, especially LH driver American cars [citation needed], had a pantograph wiper on the driver's side, with a conventional pivot on the passenger side. Asymmetric wiper arrangements are usually configured to clear more windscreen area on the driver's side, and so are mostly mirrored for left and ...
[7]: 10 The pantographs on the Westinghouse-powered cars would bounce on the aging catenary wires, then draw high currents due to improperly designed transformers. The GE-powered cars proved to have a superior pantograph design, but were still not fit for service. On March 12, entry into revenue service was delayed indefinitely.
Each motor car was powered by a single truck at the pantograph end which in turn was equipped with two 200-horsepower (150 kW) 25 Hz series wound AC motors. Using AC motors of this type resulted in poor acceleration compared to equivalent DC motors, a problem that was exacerbated by the frequent stops the MP54s would make in local commuter service.
Typically, the end cars of each 4-car unit have powered bogies, with the two middle cars being unpowered. The pantograph is located on one of the unpowered cars. [2] The specifications for all current designs (2009) describe asynchronous three-phase motors, with forced air cooling. [2]
The design of the Type 10 cars is built around the ongoing project to upgrade the CharlieCard. The upgraded CharlieCard will support proof-of-payment fares, which will allow Green Line operators to stop processing fares. The Type 10 cars incorporate this change into their design, with operators driving the train from an enclosed, full-width cab ...
Cars 2, 4, 6, 8, and 10 were each fitted with cross-arm pantographs. [ 4 ] These units were subsequently renumbered as 16-car sets X2 to X5 with the inclusion of bilevel trailer cars, and were introduced on Hikari services from November 1986.
Pantograph car No. 167 at the National Tramway Museum, Crich. The Pantograph cars were 10 trams built in 1928 by English Electric in Preston. They were numbered 167–176. These cars were single-deckers and purchased at a cost of £2,000 (equivalent to £152,209 in 2023), [6] by Blackpool Corporation Tramways. They were designed for interurban ...
