Is PATH getting new cars any time soon? I hope not, I love the ones they have now and think they're great.
NIMBY?........ I think they will be getting new cars by the end of this decade. The older cars of the fleet are from the late 1960's, were rehabbed in the 80's, but I think will soon be at the end of their useful life, although they do seem well maintained. (They also have some newer cars from the late 1980's; the ones with 3 doors per side instead of 2) Yes they are excellent, especially for the huge windows, including the extra buff window on the left side of the car ends. They have been among my favorite trains to ride. Let's hope they don't buy full-width cabs like NYC Subways have done!
BTW, did you take the ride from WTC to Newark Station? It's about the best hour of railroad sightseeing anywhere in the NY area. And cheaper than the NYC Subways. :D
