Ironically, I think PA's problem on some level is that they weren't able to maintain more than one train per day through the state. Let's lay out an alternate way things might have played out: The Broadway survives while the LSL gets cut, and Amtrak opts to maintain the Pennsylvanian to Chicago as well while the upstate services get a trim. This could easily have been justified with marginally different numbers and political calculuses (such a setup would probably serve PA and OH better than the current situation while screwing NY), particularly if the Vermonter had been maintained through to Montreal all along (even as a day train).
In such a universe, who is to say that we might not be having a messy discussion on how far the ALB-BUF trains are going to be cut back (with occasional chatter on the corridor being dropped entirely and a lot of it focusing on the Maple Leaf being the sole survivor) and the Adirondack looks like it's toast while the PA GOP is grumbling, but propping up whatever services they have to there?
Well said!
I am the beneficiary of the survival of relatively good service on the Water Level Route -- all of which arguably survived due to the vagaries of chance in the past. We've actually gained a lot (LSL, Maple Leaf, Empire Service to Niagara Falls and Buffalo Exchange St., new Syracuse station, Schenectady) since 1971, and we've only lost the Niagara Rainbow. Perhaps the critical mass of three-a-day, which we never dropped below, was sufficient to build upon.
Meanwhile, Pittsbugh-Harrisburg service seems to have lost service more often than it gained service. It also started with three a day, but one died very quickly, and two were long distance -- of which one died pretty quickly. I don't want to see my Pennsylvania neighbors suffer due to a random historical chance which could have gone the other way.
(My Ontario neighbors are already suffering due to the random vagaries of politics going worse in Canada than the US, with the Maple Leaf now being the only train to Niagara Falls Ontario.)
