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 ("as the crow flies"). It is an example of the chainage system, instead of the milepost or mileage system.
The New York City Subway system differs from other railroad chaining systems in that it uses the engineer's chain of 100 feet (~30.5 m) rather than the surveyor's chain of 66 feet (~20 m).
