Regarding the PS2 5 volt vs. 3 volt systems; is there a method to determine what sets use which, or is by date of manufacture - and does anyone know that date for the subway sets?

The cutoff point between the ps2 5 volt and 3 volt boards is early 2000s but there was overlap where both boards were being sold. The easiest way to tell is if you turn the engine upside down, the 5 volt board has a round battery charging port and the 3 volt has a rectangular 2 pin charging port. The good news for you if you stick to the engine era that you previously posted, all the engines that fit (lo-v, bmt standard, Q cars, and the R1) were made after MTH switched to the ps2 3 volt boards and some were even reissued in ps3. SIRT is 100% correct about grades.
