I have an upcoming trip NYP - CHI on the LSL. As a solo traveler I'd prefer a window seat. It sounds like from the previous posts here, the best way to get a choice of seat might be to avoid the escalator line-up and to escort myself to the West End Concourse and the signage denoting Tracks 17-21, and finding the appropriate track from there.
A couple points of clarification. Is the West End Concourse in Moynihan itself, or is that referring to Penn Station? Second, am I going to miss any pertinent information like what car to board? Is that info given at the escalator or by OBS as you reach the train itself?
