The growth of New York’s subway system

Check out this New York City subway map — it shows the growth of the subway system in order of the year each line was constructed. What’s kinda neat to see is that the subways first appeared in the Brooklyn area, not in the dense downtown area. And if you like subway maps, check out the many different NYC subway map manifestations dating back to the 19th century (or go to a local Subway sandwich shop and look at the walls).

This post is also an open challenge: the person who produces the best animated map like this for Toronto’s subway construction, and sends it to us, will receive a set of Spacing’s subway buttons (value $49). Let’s say the deadline is Friday at noon so we can post the winner by late afternoon. Click on the “continued reading” link below for the dates of Toronto’s subway expansion.

Let the animated GIF competition begin!

  1. What a wonderful idea!
    Although it would be extremely cool, and maybe more appropriate to the form of Toronto’s network if the map also included the streetcar network and radials.
    (Or continued on to show the Transit City/MoveOntario2020 plans!)

  2. Cool, but also deceptive in that it doesn’t show the network of els that originally served Manhattan and were later removed… hence the perception that “the subways [i.e., rapid transit] first appeared in the Brooklyn-area, not in the dense downtown area”.

  3. You probably could map all streetcars, radials, and bus routes based on the information at — it’s a mind-bogglingly thorough site. You wouldn’t be able to throw it together by Friday, though.

  4. Mark — not to mention the Bay/St. George interlining!

  5. The Queensway right-of-way should be shown as well, following by the Harbourfront right-of-way, Spadina right-of-way, and the first portion of the St. Clair right-of-way.

  6. Queensway (Queen) — Claude to Humber loop opened 1957/07/21.
    Harbourfront — Union Station to Spadina & Queens Quay loop: 1989/06/22.
    Spadina — Spadina Station to Union Station: 1997/09/27.
    Harbourfront — to Bathurst: 2000/07/16
    St. Clair — St. Clair Station to Vaughan: 2007/02/18.
