How does a pantograph work on an electric train?
How does a pantograph work on an electric train?
The electric transmission system for modern electric rail systems consists of an upper, weight-carrying wire (known as a catenary) from which is suspended a contact wire. The pantograph is spring-loaded and pushes a contact shoe up against the underside of the contact wire to draw the current needed to run the train.
Where was the electric HST pantograph in 1982?
During June 1982 an unusual HST set could be seen on the northern end of the WCML. At the time there were proposals for an electric version of the HST which would have a power car at each end of the train with pantograph raised.
Where was the changeover for the pantograph train?
As such, the line required railcars that featured pantographs as well as third rail shoes, and since the overhead was a very small portion of the system, only a few cars would be so equipped. The changeover occurred at the grade crossing at East Prairie]
Which is the best description of a pantograph?
Pantograph (transport) A pantograph (or “pan”, or “panto”) is an apparatus mounted on the roof of an electric train, tram or electric bus to collect power through contact with an overhead line. It is a common type of current collector.

Why are Overhead pantographs used instead of third rails?
These may consist of physical ground-level infrastructure, or use energy stored in battery packs to travel over short distances without overhead wiring. Overhead pantographs are sometimes used as alternatives to third rails because third rails can ice over in certain winter weather conditions.
