The PRR had a yard that served the GM auto plant in Linden, NJ. I don't know which side of Linden Yard the bridge to Staten Island is, but auto racks out of Linden would have been heading west. The attached picture is of the PRR Doremus Avenue yard in Newark, NJ which has a lot of auto racks in it. The PRR South Kaearny yard loads truck trains. Maybe it loaded double stacks.
Here is contrary information though, on the RR.NET NJ Transit forum probably, on the topic "NEC and doublestacks." John Gaughran- Jtgshu was an NJ Transit engineer, a prolific poster here whose sudden death August 26th 2013 shocked many of us.

Its been a while, but in late 2001, early 2002, CR sent a train out of Oak Island yard in Newark, NJ on the NEC with a double stack. It made it as far as the former Staten Island RR bridge in Linden NJ..........the bridge stopped it!
IIRC, the clearance charts CR had were never updated with the various trackwork/rail/tie replacement over the years. They had info that showed it would have cleared, where in reality, it didn't.
the worse part was was that it was on the inner tracks, which yanked down the wire on the outer tracks, and basically the entire NEC through Northern NJ was shut down for the night. It was QUITE a mess!!!!
Other than NYP, I BELIEVE that is one of the lowest points on the NEC, at the SIRR bridge. I think the other really low clearance points are down by Philly.

John says "the clearance charts CR had were never updated." Maybe that's why the PC or Conrail tried to put a train of loaded trilevels through Weehawken tunnel one time, over the protests of the engineer. It got part way through and ground to a halt, making convertibles of the cars on the top level. I heard that the railroad officials got the damaged cars, which were expensive cars.
For more on this on RR.NET google "NEC and doublestacks."
