In a movable bridge that uses a rigid overhead rail, there is a need to transition from the catenary wire system into an overhead conductor rail at the bridge portal (the last traction current pylon before the movable bridge). For example, the power supply can be done through a catenary wire system near a swing bridge. The catenary wire ...
Name of system Location Date (from) Date (to) Notes Duluth: 15 October 1931 15 May 1957 Twin City Rapid Transit Company: Minneapolis: 5 May 1922 22 May 1923 Experimental. One-wire trolley pole overhead, and a shoe to streetcar rails below to complete the circuit.
Overhead over a switch in Toronto: Two runners for pantographs flank the trolley pole frog. Trams or light rail cars equipped with pantographs normally cannot operate on lines with overhead wiring designed for trolley-pole collection. For this reason, these systems and a few others worldwide retain use of trolley poles, even on new streetcars ...
Busscar trolleybus in São Paulo, Brazil Solaris trolleybus in Landskrona, Sweden Video of a trolleybus in Ghent, Belgium. A trolleybus (also known as trolley bus, trolley coach, trackless trolley, trackless tram – in the 1910s and 1920s [1] – or trolley [2] [3]) is an electric bus that draws power from dual overhead wires (generally suspended from roadside posts) using spring-loaded ...
The pantograph was an improvement on the simple trolley pole, which prevailed up to that time, primarily because the pantograph allows an electric-rail vehicle to travel at much higher speeds without losing contact with the overhead lines, e.g. due to dewirement of the trolley pole.
Trolley pole wheel on top of the trolley pole of Twin City Rapid Transit Company No. 1300. A current collector (often called a "pickup") is a device used in trolleybuses, trams, electric locomotives and EMUs to carry electric power from overhead lines, electric third rails, or ground-level power supplies to the electrical equipment of the vehicles.
Used both third rail DC (1200 V) and overhead line AC (6.3 kV 25 Hz) until 1955. Also uses German standard 15 kV AC 16 2/3 Hz overhead electrification on the section between Neugraben and Stade on line S3, opened in December 2007.
A trolleytruck (also known as a freight trolley or trolley truck [1]) is a trolleybus-like vehicle used for carrying cargo instead of passengers. A trolleytruck is usually a type of electric truck powered by two overhead wires , from which it draws electricity using two trolley poles .
