Holland Trackstar [1] in Washington Mills, New York. 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 ...
The vast majority of rapid transit systems use 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge.Some of the largest and oldest subway systems in the world use standard gauge in agreement with the country wide dominant usage for track gauge, e.g. London Underground (1863), Chicago "L" (1892), Vienna Metro (1898), Paris Métro (1900), Berlin U-Bahn (1902), New York City Subway (1904), Stockholm ...

New York City Subway chaining is a method to precisely specify locations along the New York City Subway lines. It measures distances from a fixed point, called chaining zero , following the twists and turns of the railroad line, so that the distance described is understood to be the "railroad distance," not the distance by the most direct route ...
