Sometimes I do wonder about the sense of urgency of Amtrak crews, specifically on late trains at long stops.I believe is double tracked from LA to El Paso. At one time UP had grand plans of competing with the BNSF's LA-CHI route (LOL).
Amtrak is part of the problem too. Watch this late SL when it arrives in Tuscon on Youtube. Tuscon is a 50 minute schedule service stop, it takes 20 minutes to refill the Genesis with one fuel truck and for INS to let Rover walk the train, yet watch a 5 hour late SL sit there for 30 minutes more. I wander if Amtrak is as concerned about time as the pax.
On the flip side, some crews do care. One time I saw a conductor just board everyone (coach and sleepers) at one door to prevent a pull-down move at a station. The sleeper passengers had to walk through the train, but it saved a few minutes time.
