had grandfather who was Pullman conductor. Usually ran Bristol Va - Harrisburg Pa. Had 4 - 5 pullmans from Bristol. At Roanoke stayeed with 1 car and picked up others. The others inbounds went on with another conductor to various cities. His car proceeded somewhere ( maybe Buffalo ) by another onductor with other cars.
He supervised the porters. He hardly ever got the same porter as the porter stayed with the car. At both Buffalo and Bristol his inbound pullman car rotated to other cities such as ATL ( major overhaul facility ) , New Orleans, Memphis, Nashville, Depending on configuration. Not sure but maybe the section brdroom. Often Pullman would run extra cars.
The point is thr Amtrak service manager should rotate with different assignments than the OBS so there is not any manager getting cozy with all crew members. rx. OBS goes to point A every 7 days and manager goes every 6. Then rotates to other train routes.
