> The major IRT lines save for the 7 operate mixed fleets of NTT and R62/A equipment, none of which share door positions IIRC Do they not? The R62 and R142 cars are both the same number of doors and of the same length [1] [2], and the moving platforms at some stations would, I think, require the doors be in approximately the same spot, no? > The Eastern Division still uses old rolling stock like R42s from time to time. Yes, but the R42 and R143/R160 have the same overall length and door count (and the spacing appears to be the same as well) [3] [4] As an aside: it’s quite frustrating that the measurements given on the datasheets are of varying frequency.

They do not. In R62s, doors are parallel to each other on each side of the car. [1] However, it was found that because passengers like to crowd at doors, passengers wishing to exit from either side would just crowd in the same place. To ease crowding, the NTTs have wider, offset doors, so that not everybody is standing in the same place [2] The gap fillers at Union Square are very long, which is why they can line up with multiple door positions.
