• Caption: R62A #1936, built by Bombardier in the mid-1980s, is on one end of a shuttle train at Grand Central. The 42nd Street Shuttle operates between Grand Central and Times Square and was part of the Interborough Rapid Transit Company's original subway line opened in 1904 (the first subway in NYC). In 1918 the IRT altered service so that trains on the Broadway/7th Ave Line and the Lexington Ave Line no longer crossed over at 42nd St, resulting in the creation of the shuttle. The shuttle has three tracks (the fourth one having been filled in for platforms at either end), each with a train that runs independently of the others. All three tracks connect to the rest of the system at one end or the other, but no through routing is possible. (September 14, 2010)
