Why yes indeed anytime equipment moves is some type of equipment move
But unless it was an Army-Navy game special, or a fantrip, I doubt it was a revenue move.
I forget which year, but I was on a fantrip using ex-Reading blueliners that was supposed to have taken the highline, but a freight derailment fouling the now removed zoo junction to Amtrak's northeast corridor connection gave us the thrill of going through 30th St lower level.
Sometime between 1996-1998 I rode a promotional special that some Reading area chamber of commerce ran to the Vanity Fair outlet mall in Wyomissing, at which time that zoo connection was gone, so in order to get onto the railroad to Reading we went south out of 30th St lower level to Arsenal, changed ends, and went north over the highline. Alternatively they could have gone through the center city tunnel and out the Norristown line, but I bet they figured that'd be more complicated: I think we had at least 10 Amfleet; diesel locomotive; would have needed to involve another agency, SEPTA as well as Amtrak and the freight railroad; probably would have needed another pilot crew for SEPTA territory.
On board that trip someone mentioned there had been a Metroliner scheduled to skip Philly that used the highline. It's hard to figure how the schedulers figured that was faster than going through 30th St, I always imagined the highline was supposed to keep slow freight trains from getting in passenger trains' way.
Circa 1979-1982 NRHS convention in Toronto fantrip used their Union Station freight bypass, which trip personnel called 'high line', even though its grade was below Union Station's.
