PS: NJT Multilevel cars are not regularly used on the Atlantic City Line.
Most AC Line trains are about four single-level cars on average.
This train looks to be a deadhead move between the MMC and Morrisville Yard judging by the length.
For the record the only AC Line trains that regularly used assigned (special) multilevel cars was the ACES Train
which ran from NYP-NWK nonstop to Frankford Junction/Shore Tower changing direction to/from the AC Line.
That service used both a diesel locomotive and an electric locomotive (remember the ALP44?) at either end.
