I've been in the station when they swapped both loco & consist... They pulled in i think it was 4105 right up to the bumping block and then one of those rebuilt work units shuffled in 6-7 comets. I guess one set was facing one way & the other was facing the other way and they just needed to have a train ready for that departure. It was idling prime mover only till they hooked the cars up. Not as loud, but still very noticeable vs west ended. Then there was the time they had an F40 lashed to a geep shuffling consists around mid-day as the cab cars sat by themselves. When they throttled up to mate one of the cabs it totally startled a bunch of people much to my amusement.
Next stop the square, journal square station next!
