A track geometry car (also known as a track recording car) is an automated track inspection vehicle on a rail transport system used to test several parameters of the track geometry without obstructing normal railroad operations. Some of the parameters generally measured include position, curvature, alignment of the track, smoothness, and the ...
The most common use of the term "track gauge" refers to the transverse distance between the inside surfaces of the two load-bearing rails of a railway track, usually measured at 12.7 millimetres (0.50 inches) to 15.9 millimetres (0.63 inches) below the top of the rail head in order to clear worn corners and allow for rail heads having sloping ...
Track gauge or rail gauge (also known as track gage in North America [8]) is the distance between the inner sides (gauge sides) of the heads of the two load bearing rails that make up a single railway line. Each country uses different gauges for different types of trains.
Original definition of Brunel's broad gauge. This rail gauge was soon changed to 7 ft 1 ⁄ 4 in (2,140 mm) [105] to ease running in curves. 2,140 mm 7 ft 1 ⁄ 4 in: South Africa East London and Table Bay harbour railways England Brunel's Great Western Railway until converted to standard gauge by May 1892, see Great Western Railway The "gauge ...
The Portland Company was formed to build locomotives of this gauge for use on the local rail system. [3] The gauge was known as "Texas gauge" while required by Texas law until 1875, [4] and used by the New Orleans, Opelousas and Great Western Railroad (NOO&GW) until 1872, and by the Texas and New Orleans Railroad until 1876. The New England ...
The time interval may be controlled by a level crossing predictor, an electronic device which is connected to the rails of a railroad track, and activates the crossing's warning devices (lights, bells, gates, etc.) at a consistent interval prior to the arrival of a train at a level crossing. [1]
The detectors would transmit their data via wired links to remote read-outs in stations, offices or interlocking towers, where a stylus-and-cylinder gauge would record a reading for every axle; a defect would register a sharp spike on the graph and an alarm would sound or a visible signal would be given to the train crew.
In 1886, the southern railroads agreed to coordinate changing gauge on all their tracks. After considerable debate and planning, most of the southern rail network was converted from 5 ft (1,524 mm) gauge to 4 ft 9 in (1,448 mm) gauge, then the standard of the Pennsylvania Railroad, over two days beginning on May 31, 1886. Over a period of 36 ...
