NYCTA uses 127.3 CTCSS.
The train-to-dispatch and dispatch-to-train frequencies and the yard channel are the most heavily used from an operational standpoint, and of the greatest interest to scanning enthusiasts. All frequencies in Table 1 and Table 3 are fully receivable in the subway.
You may also want to refer to NYCTA Radio Codes.

Prior to "unification" in June of 1940, the BMT tracks were operated by the Brooklyn-Manhattan Transportation Company, now designated as division B1. The B2 division is trackage that was owned by the city-run Independant subway. Division A is the former territory of the Interborough Rapid Transit Company (IRT). Incidentally, the reason for the "A" and the "B*" designations is that trains from division B are wider (by about a foot and a half) than on A, thus are completely seperate operationally. However, IND and BMT specs are identical, and in fact there have been many connections built between tracks formerly owned by the IND and the BMT (i.e. Chrystie Street ("B" and "D" trains, plus an unused connection to the Williamsburg Bridge (Former "K" train), 63rd Street (future use only), Queens Plaza ("R" train), Church Ave/Ditmas Ave (Culver line/"F" train) and Prospect park (Brighton line/Q train). At these locations, when a train goes from one territory into another, there is a sign indicating to the train operator to switch radio channels as required.
