What is an overhead train called?

An elevated railway or elevated train (also known as an el train for short) is a rapid transit railway with the tracks above street level on a viaduct or other elevated structure (usually constructed from steel, cast iron, concrete, or bricks).

What is a train user called?

A train driver, engine driver, engineman or locomotive driver, commonly known as an engineer in the United States and Canada, and also as a locomotive handler, locomotive operator, train operator, or motorman, is a person who drives a train or a locomotive.

What does OLE stand for railway?

Overhead line equipment
Overhead line equipment (OLE) refers to the overhead wires and supporting infrastructure that carry electricity at 25,000 volts to power electric trains.

What is called elasticity of overhead equipment?

Increase in tension reduces the static elasticity of the OHE and makes it more uniform and thus improves the dynamic behaviour and current collection. Contact and catenary wires are given tension of about 1,000 kg each so as to limit the lateral stresses exerted on the masts and foundations due to increase in tension.

Why 25kV is used in railway traction system?

The main reason for 25kV voltage used in railway is, that 25 kV AC more economical than 1.5kV DC voltage system. Since 25kV voltage system has higher voltage, the higher voltage reduces the current flow through conductor; this reflects to reduce the conductor size.

What is a student telegrapher called?

HAM—Poor telegrapher or student. HAND BOMBER or HAND GRENADE—Engine without automatic stoker, which is hand-fired. HAND-ON—Train order or company mail caught with the hoop or without stopping.

What is the minimum safe distance from the Ole?

Danger from electric current You should behave as if the overhead line equipment (OLE) is live at all times. Make sure you and anything you hold does not come any closer than 2.75 meters (9 foot) of any live OLE.

Which wire is used in Railway?

Eland Cables’ catenary wires were designed specifically for the Railway industry. Available in Bronze II (PADS: 91/012330) or in Hard-Drawn Copper (PADS 91/010269), they are used to transmit power along the length of an overhead system which is then connected to the contact wire by dropper wires.

What type of wire is used for overhead?

The most common conductor in use for transmission today is aluminum conductor steel reinforced (ACSR). Also seeing much use is all-aluminum-alloy conductor (AAAC). Aluminum is used because it has about half the weight and lower cost of a comparable resistance copper cable.

Why is AC preferred over DC?

Answer: Ac is more preferred than dc because it is easy to maintain and change the voltage of ac for transmission and distribution purpose. Plant cost of ac transmission is much lower compared to dc transimission. When fault occurs it is easy to interrupt ac supply.

Is there such a thing as an elevated railway?

The railway may be broad-gauge, standard-gauge or narrow-gauge railway, light rail, monorail, or a suspension railway. Elevated railways are normally found in urban areas where there would otherwise be multiple level crossings. Usually, the tracks of elevated railways that run on steel viaducts can be seen from street level.

What was the name of the elevated train in Liverpool?

Liverpool Overhead Railway, May 1951. NS 93 train on an elevated portion of the line 5 of the Santiago Metro.

What was the name of the Elevated Railroad in New York?

History. The New York West Side and Yonkers Patent Railway operated with cable cars from 1868 to 1870, thereafter locomotive-hauled. This was followed by the Manhattan Railway in 1875, the South Side Elevated Railroad, Chicago (1892–), and the elevated lines of the Boston Elevated Railway (1901–).

Where do two Schwebebahn trains meet above street?
