A few old subway cars have been freed from their displays at the NYC Transit Museum and will be running on the V line over the holidays:
amNew York: Hop on Board…: The old cars are usually stored at the New York City Transit Museum in Brooklyn Heights, but every Sunday this December, the MTA will operate a 1930s to 1940s six-car train on the V line, running from Queens Plaza to Second Avenue in Manhattan, a part of the line's run. The museum has 88 of the vintage cars, 20 of which are on display. This year's holiday line is made up of cars from the R-1 through R-9 series that used to operate on the IND and BMT lines.
