Downstairs they have several cars on display, everything from old gate cars used on the elevated, to IRT low v's, BMT standards, and IND R1/R9, an R11, R16, R30, and R36. They also have a recently retired R46 as well as some other equipment on display.
Once we were done there we got on an R46 equipped "A" train to penn station. We had lunch at Penn station (which has a food court unlike King Street Stn. in Seattle) we walked back to PABT and checked out the neighborhood a bit more. After seeing bad traffic entering the lincoln tunnel we decided to take an earlier 320. Once back at the hotel and with our bags the hotel van took us to Seacacus Jct. and we got on an NJT northeast corridor line train to newark airport.
A couple of comments about fare collection, the NYC metro card needs to be replaced with a contact-less system, half the turnstiles did not like one or both of our cards, also the NJT ticketing system seems wasteful with ticket vending machines all over the place that need to be maintained, and the Parkeon wayfarer devices on the buses seem to spit out a lot of paper receipts for no reason at all. Im sure its been done this way for 100 years and probably not going to change soon. This concludes the trip to NY.
