Unless things have change aren't PATH cars shorter than any NY city subway cars. Running PATH and the subway together would cause a turf war tween FRA and Federal transit authority. (FTA). Do PATH cars have MTA trip arms? Do I remember correctly that IRT trip arms on different sides from IND and BMT?
Yes, the PATH system does have trip arms. They are at track level on the left side. This would be the same the cars on the B division of the NYC Subway. The trip arms on the A division (former IRT are on the right side of the tracks.
That would cause an issue if there was ever a cross operation between systems.
I did hear at one time (and don't hold me on this) that IRT cars might have a problem navigating the tight curve ratio between the Christopher St station and the tunnel under the Hudson. Something about how the trucks are positioned under the cars of PATH vs NYC Subway cars. Since I don't spend time comparing the position of wheel trucks on subway cars I can't comment further.
BTW just a minor point on the length of PATH cars vs IRT cars - IRT (R62, R 142) cars are actually 51 feet 4 inches measured from the of the anti-climbers. PA5 cars are also 9.2 feet wide vs IRT cars are 8.6 feet wide.
