Yeah, I've always felt that the Boston section of the LSL is sort of a weird outlier service because it's the only single-level LD "train" that doesn't terminate in NYP.
What I wonder is could it possibly make sense to stop splitting/combining the LSL, and instead just run the whole thing into NYP and then onto BOS (via the NEC)? The full trip to Boston would take a
bit longer, but likely not that much considering it wouldn't have to spend nearly as long in ALB (so maybe a 2 hour longer ride to Boston now, while shortening the trip to New York). Doing this would give all passengers access to all onboard services like the
diner Sleeper Lounge, baggage car, and Cafe/Business car for the entire trip, instead of losing some east of Albany. It would also provide a direct link between the Empire Corridor and the NEC, and make it easier for cars to be serviced or repaired if need be.
And though Lake Shore service to PIT, SPG, WOR, and FRA would be lost, it could be replaced by that proposed BOS - PIT/ALB corridor discussed
here. Yes, there wouldn't be any more direct service from those stations to points west of ALB, but don't many AUers choose to avoid staying in the Boston sleeper anyway and instead go coach or BC to ALB, where they switch to an NY sleeper? So needing to transfer in Albany definitely doesn't seem to be the worst thing in the world.
Anyhow, that's just an idea that likely will come crashing down upon closer inspection, but I'm putting it out there anyway.
