In the U. S., chaining is a method by which railroads precisely measure and specify locations along the line. 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 ("as the crow flies").

  • In the U. S., chaining is a method by which railroads precisely measure and specify locations along the line. 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 ("as the crow flies"). At least three different methods of measuring distance on railroads are in use in the United States: the milepost or mileage system, where distances are usually measured in miles and hundredths, the engineer's chain of 100 feet (~30.5 m) in length, and the Gunter's chain of 66 feet (1/80 of a mile).
