plus there would need to be a Switching Crew in Pittsburgh in addition to the Crossover and any other needed track work and any Ransom,er Payments the Class Is would ask for!
Lots more than $50,000 involved!
No there wouldn't. This was explicitly laid out in the PIP:
It requires a switch on both ends so that road crews on these trains can both set out and pick up the cars without requiring a yard switching locomotive and crew. Track 1A also requires 480 volt ground power. A yard switching locomotive and crew would be cost prohibitive for the sake of making so few moves every 24 hours.
Literally no other track work or payments needed, as there would be no change to the operation of either train other than the switching at the station.
