Supposedly they'll still allow PV's to be hitched on at terminals where regularly scheduled trains dwell for more than 30 minutes. But no intermediate stops like Huntington (Dearing, Braddock Inn, etc) or Cincinnati (Moonlight Dome) because it delays trains for "paying customers"… which is bullshit, because PV owners are paying customers too.
Currently PV owners have until the end of April to move their cars to wherever they're going to live, whether that brings them home, or they start paying a premium for track space at a major terminal to keep their cars out there trying to make money.
This will kill the New River Train (used Amtrak crews) and cause much difficulty for mainline steam programs that were going to use the Amtrak umbrella for operational security and insurance. Mr Bennett Levin's E units will still run (for the last time, thanks to PTC) in May though.
A railfan wiser than me said some time ago that the pendulum for this sort of thing is always swinging. It swung way out to one side during the NS 21st century steam program, and now it's swinging back the other way. Buckle up and pray for that return swing, folks.
