A traction motor is an electric motor used for propulsion of a vehicle, such as an electric locomotive or electric roadway vehicle.
A traction power station is a power station that produces only traction current, that is, electric current used for railways, trams, trolleybuses or other conveyances.
A traction substation, traction current converter plant or traction power substation (TPSS) is an electrical substation that converts electric power from the form provided by the electrical power industry for public utility service to an appropriate voltage, current type and frequency to supply railways, trams (streetcars) or trolleybuses with traction current.
A train is a form of transport consisting of a series of connected vehicles that generally runs along a rail track to transport cargo or passengers.
A tram (also tramcar; and in North America streetcar, trolley or trolley car) is a rail vehicle which runs on tramway tracks along public urban streets, and also sometimes on a segregated right of way.
A transformer is a static electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
A trolley pole is a tapered cylindrical pole of wood or metal, used to transfer electricity from a "live" overhead wire to the control and the electric traction motors of a tram or trolley bus.
A trolleybus (also known as trolley bus, trolley coach, trackless trolley, trackless tram Joyce, J.; King, J. S.; and Newman, A. G. (1986). British Trolleybus Systems, pp. 9, 12. London: Ian Allan Publishing.. or trolleyDunbar, Charles S. (1967). Buses, Trolleys & Trams. Paul Hamlyn Ltd. (UK). Republished 2004 with or 9780753709702.) is an electric bus that draws power from overhead wires (generally suspended from roadside posts) using spring-loaded trolley poles.
The Tyne and Wear Metro, referred to locally as simply The Metro, is a rapid transit and light rail system in North East England, serving Newcastle upon Tyne, Gateshead, South Tyneside, North Tyneside and Sunderland in the Tyne and Wear region.
The United States of America (USA), commonly known as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major self-governing territories, and various possessions.
The universal motor is a type of electric motor that can operate on either AC or DC power.
A variable-frequency drive (VFD; also termed adjustable-frequency drive, “variable-voltage/variable-frequency (VVVF) drive”, variable speed drive, AC drive, micro drive or inverter drive) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.
Vienna (Wien) is the federal capital and largest city of Austria and one of the nine states of Austria.
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
Voltage, electric potential difference, electric pressure or electric tension (formally denoted or, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's circuit laws) is the difference in electric potential between two points.
A well car, also known as a double-stack car or stack car (also well wagon), is a type of railroad car specially designed to carry intermodal containers (shipping containers) used in intermodal freight transport.
Wellington (Te Whanganui-a-Tara) is the capital city and second most populous urban area of New Zealand, with residents.
