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 ...
The first locomotive to be fitted with the pantograph was Class 86 No 86244, during February 1980. The pantograph is the mainstay within the UK railway system, where it is used on most overhead electric locomotives and EMUs. It has also been exported across the world, being used on the US high speed train Acela and the Eurostar Class 373.
Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...

The car previously had a special pantograph that was used to test and measure overhead lines. #10003, an unnamed Acela -based track geometry car. It is periodically inserted into an Acela Express consist between a power car (locomotive) and the nearest end car, resulting in a train with two power cars and seven intermediate cars rather than the ...
On curves, the "straight" wire between the supports causes the contact point to cross over the surface of the pantograph as the train travels around the curve. The movement of the contact wire across the head of the pantograph is called the "sweep". The zigzagging of the overhead line is not required for trolley poles.
On 3 July 2014, a WAP-5 set an Indian speed record by hauling a train between Delhi and Agra at a speed of 160 km/h (99 mph). [2] The locomotive has regenerative braking , flexible gear coupling, wheel-mounted disc brakes , and a potential for speed enhancement to 200 km/h (120 mph).
The trains will feature regenerative braking and Hitachi Rail's low noise pantograph, whilst also being 15% lighter and feature 30% more seats than comparable high speed trains in Europe. [ 26 ] [ 21 ] The trains will also be the fastest trains in the United Kingdom and Europe.
