Unused New York City Subway service labels

From Wikipedia, the free encyclopedia

Several New York City Subway service labels have never been used, but have appeared on rollsigns. DD, FF and MM are covered in the D, F and M articles. The others are included here.

[edit] IRT numbers

An R62A car in Corona Yard displays a 12 sign.
An R62/R62A-class car operating on the 42nd Street Shuttle erroneously shows an upside down 11 sign instead of the usual black S for shuttles. The purple color currently corresponds to the IRT Flushing Line.

Current rollsigns include the following:

  • Green 8, 10, 11 and 12 (the same color as the 4, 5 and 6)
  • Purple 11 (the same color as the 7 and its diamond service)
  • Red 13 (the same color as the 1, 2 and 3)
  • Red 9, unused since May 27, 2005

It is likely that these were assigned arbitrarily, for use if MTA changed express from diamond to a separate number.

[edit] IND/BMT letters

  • P, T, U, X and Y appear on some current rollsigns as a black letter on a white circle. No current services use this color, so the signs would likely be patched if any of these services were to become permanent. T is the planned label for the new Second Avenue Line, and would be colored turquoise.
  • I and O have never been used due to their similarity to the numerals 1 and 0 respectively.
  • P was skipped in the 1960 assignment of letters to BMT services.
  • X is also on the R-44/46 side sign with the destinations "21st St Queensbridge" and "World Trade Center" "via 6th Av.". Years ago, there were ideas to run such a service, but it never came about.
  • Y was once planned for a Canarsie skip-stop service (before "K" was chosen), but in either case, it never ran.
  • The JFK Express bullet, featuring an airplane inside a blue circle, was used from 1978–1990, and is still present on rollsigns on various IND line trains today.
