Turns out a group, Atlantic Rail Tours LLC of South Carolina, was getting together an add-on excursion on the Pennsy, in time for Pittsburgh's Anthrocon this year:

Note I said *was*. They couldn't pull it off this year but aims for 2020:Anthrotracks will take place aboard beautifully restored and maintained mid-20th-century railcars that will be carried on a round-trip from New York City to Pittsburgh — departing New York westbound on July 4 and returning east on July 8 — coupled to Amtrak’s Pennsylvanian train, which plies the route daily in both directions and is financially supported by the Pennsylvania Department of Transportation. The chartered railcars are owned or managed by the Morristown and Erie Railway, a short line railroad in northern New Jersey. In addition to New York, passengers will also be able to board westbound and alight eastbound at Newark and Trenton, N.J. and Philadelphia and Harrisburg, Pa.
Those wishing to travel with Anthrotracks can choose between private sleeping car accommodations — a roomette for a solo traveler or a double bedroom shared by two passengers — and comfortable day seating in a lounge or parlor car. Those reserving sleeping accommodations will be able to use the railcars as their lodging for four nights while they are stationary at Pittsburgh’s Amtrak station, which is conveniently located three blocks from the Lawrence Convention Center. Both sleeping car and day passengers will have unlimited access to the activity cars and food and beverages are included in the ticket price for both classes of service.

Thank you for your interest in Anthrotracks. After going over the numbers several times, lengthy discussions among our team, and consulting with trusted advisors, we have reached the difficult decision not to move forward with Anthrotracks 2019 (a chartered railcar excursion to/from Pittsburgh for Anthrocon 2019). However, this is not the end of Anthrotracks as an idea — rather, we hope it is only the beginning.
We apologize for any inconvenience to anyone who may have made plans to travel or stay with us for Anthrocon 2019. If any payments were made, a full refund will be issued.
