As to the travel times...doesn't the Penny have to change engines at Philly anyway? Seeing as that is probably the case, could Amtrak move the engine swap to Harrisburg if there was going to be a noticeable drop in travel times (and I think most of us can agree that a 30 minute cut in travel times would normally be worth such a move)?
I don't know what exactly happens in Philly but they definitely do already change engines in Harrisburg.
No. The
Pennsylvanian changes from electric to diesel and vice versa, in Philadelphia. Te change involves taking one engine off one end of the train and tacking on the other engine at the other end. The engine change is unlikely to move to Harrisburg since there is no engine maintenance/stabling facility in Harrisburg anymore. Also an engine change where the engine has to be taken off and added to the same end is likely to take more time than what happens in Philadelphia.
Besides the logistic necessity of changing power in PHL, the equipment used on the
Pennsylvanian requires it. AFAIK, neither Amfleet II's or Viewliners have trainline cabling or connections for push-pull operation. Since those cars in the consist would prevent a cab on one end from communicating with a locomotive on the other end, trains with Amfleet II or Viewliners have to be pulled by a locomotive at all times. Unless Amtrak wanted to emulate the PRR operation of most western trains and run the
Pennsylvanian through Philadelphia bypassing 30th Street (eliminating the need to change directions), the power swap, including moving power to the other end of the train, must be made at PHL. I used to watch them do that with the
Pennsylvanian from my office across the river from 30th Street, and it was well choreographed. There was not much time wasted.
The Pennsylvania Railroad had a sleeper-only overnight train between New York and Pittsburgh that included 30th Street as a stop. It departed New York and Pittsburgh late night and arrived at the other end in the early morning. The westbound train ran backwards between New York and Philadelphia. In Philadelphia, the power changed ends and additional sleeping cars were added for the trip to Pittsburgh. The eastbound train did the opposite. Sleeping cars opened early in New York, Philadelphia and Pittsburgh to allow passengers to turn in before the late night departure of the train. For the eastbound train (which arrived 30th Street Station before 6am), the Philadelphia sleeping car passengers could stay in their rooms until 7:45am. Basically, it was a hotel on rails.
When I was a teenager, my dad had regular business trips to Pittsburgh (from Philadelphia). He usually flew out to PIT on TWA, but I talked (badgered?) him into trying the train just once. He did (maybe just to shut me up). Afterwards, he told me it was a nice trip, but he wasn't convincing. What was convincing was that it was the one and only time he took the train to Pittsburgh. I think he wanted to spare me the gory details.
By the way, that train was called the Pittsburgher. Westbound it was PRR train 61. Eastbound it was
PRR 60.
