This would also mean staffing the additional car, moving passengers into new rooms and remaking these rooms for the next trip out. In addition, which train would lose it's sleeper for this ricochet from NYP and back?
None would - the Viewliner that should have been making the trip from Chicago was sitting in New York with the rest of the Cardinal's consist, and it could have been staffed by the same TAS's that manned the train from Chicago. OK, yeah, they would have had to make an extra switching move to tack the Viewliner onto the tail end of another train from NYP - WAS, and then another move to pull it off the tail end at WAS (which could likely be done at the same time as the engine was being changed out). Perhaps "pretty pissed" were stronger than I intended, but I would be mighty disappointed if I was planning on riding in my room all the way to NYP and ended up riding in coach for the last 5 hours while the sleeper car I should be riding in sat unused in New York.
