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).

Famous quotes containing the words york, city and/or subway:
“New York loves itself in an unkind and fanatical way.”
—Mason Cooley (b. 1927)
“The city is recruited from the country. In the year 1805, it is said, every legitimate monarch in Europe was imbecile. The city would have died out, rotted, and exploded, long ago, but that it was reinforced from the fields. It is only country which came to town day before yesterday, that is city and court today.”
—Ralph Waldo Emerson (1803–1882)
“In New York—whose subway trains in particular have been “tattooed” with a brio and an energy to put our own rude practitioners to shame—not an inch of free space is spared except that of advertisements.... Even the most chronically dispossessed appear prepared to endorse the legitimacy of the “haves.””
—Gilbert Adair, British author, critic. “Cleaning and Cleansing,” Myths and Memories (1986)
