Number of trains vs tonnage hauled are two different things. Maybe they have a pair of trains on this line, but they are usually fully DPU. And yes-- the NS flavor of PSR is really cutting to the bone, and let shareholders, the board and the STB speak for Squires.. if they want to oust him based on what's going on they will, but we saw this with CSX at first.
At some point they'll relaunch growth mode whether this regime or the next, and relatively speaking these miles vs tons doesn't make a lot of sense to maintain a signal system and/or siding capacity. It's a PSR model 101... right size the operation to the volume. But dropping the line entirely and redrawing the map I don't see that... I'm thinking the piece is alluding to rumors that surface every so often about NS routing trains over RBNM and getting from Scranton to Reading.
Before NS had its own line to reach PAS, that could have been a consideration, but in this case why would you divest now just to swap to another line? That's a lot of effort, and you need to pass the sniff test with your investors. At some point too NS will look to expand their intermodal franchise, and the actual extension of Mechanicville into the Crescent Corridor (IE adding a dedicated pair of north-south trains), not just having a fancy map with dots connected, is what we'll see.
The story is not yet told for this line, sorry to see it dipped in traffic but again no one could foresee the PSR fad for NS that is playing out, so hopefully we are through that sooner rather than later.
