Not to start a premature fussin' match, but what's the process for moving across lobato trestle with the equipment you describe?
DO YOU:
Do you run 463 and the freight across separate?
Then break off 497 and run it across alone?
Then run the 48x regular passenger consist across like a normal double header?
Then do you back 463 and freight down onto 497 and pull the 48x and passenger consist forward to 497, essentially trapping it in the middle?
OR DO YOU:
Do you break 463 through 497 off from 48x somewhere short of the trestle, running 463/freight/497 across the trestle intact, where they wait for the 48x and passengers to pull forward and recouple...
OR DO YOU:
Put 463 at the front, 48x in the middle and 497 at the very back to shove, thus not even slowing down at Lobato!??
