So I'm looking at the schedule for the Lake Shore Limited and I'm left wondering: Just how does it make any sense?
*Sigh*. It's a long series of incremental changes made for many reasons.
The eastbound leaves out of Chicago several hours later than desirable, a change which was made in order to catch transferring passengers from late-arriving trains in Chicago, when most of the western trains were arriving late. Amtrak has plans to reschedule this earlier (to roughly 6:00 PM)... but that depends on rescheduling the Capitol Limited later to catch the late connections... which means they're waiting for the CSX construction in Cumberland to finish... etc. This is all in the 2011 "Performance Improvement Plan" for the LSL.
Eastbound, the Albany-NY section has large delays built in in order to deal with Metro-North's rush hour.
There is padding in other sections due to lack of track capacity, notably around Schenectady.
Westbound, the LSL is designed to arrive in Chicago in the morning, and the rest of the schedule is built around that. This makes plenty of sense. Unfortunately, due to slower-than-desirable speeds, this doesn't make for the correct departure times back east.
It's not terribly badly designed for the Empire Corridor, but in the high travel zone it is receive or discharge only, so it really isn't actually useful for there.
You're wrong about the high travel zone.
The LSL is not "receive or discharge only" until you get to Albany. The LSL is used for upstate NY to Chicago travel. In very large quantities. This is the bread and butter clientele for the train.
The PIP explained all of this. Top city pairs for ridership, in order:
(1) Chicago-NY
(2) Chicago-Buffalo
(3) Chicago-Syracuse
(4) Chicago-Albany
(5) Chicago-Rochester
(6) Chicago-Boston
(7) New York-Syracuse
(8) Chicago-Toledo
....
The LSL also provides the fourth frequency for upstate to NYC, and that attracts a fair number of passengers.
The "Western Empire Corridor" (west of Albany) has been the area seeing passenger growth in recent years. The "Southern Empire Corridor" (south of Albany) has been seeing flat and declining passenger counts; there are actually too many trains running purely from Albany-NYC, and some of them should be extended.
But while Ohio offers great potential for corridor use (which is where the frequent trips, and therefore the money is, as well as the potential for expanded Amtrak service),
The good Ohio corridor is Cleveland-Columbus-Cincinnati, which is not the LSL route. Detroit-Toledo-Cleveland would work too, but that also requires new service on currently freight-only tracks.
Toledo-Chicago is already well served westbound. And it will be well-served eastbound if the LSL gets back to departing Chicago at 6:00 PM, or even 7:00 PM.
With the current train speeds, there is no way to serve Cleveland in decent hours on the same train serving NYC-Chicago trips, Boston-Chicago trips, or upstate NY to Chicago trips. In fact, the only way to get better Cleveland service is to run a second frequency.
in the d I can't really see a good reason not to push back the New York and Boston departures by about 2-2.5 hours
This wouldn't improve Ohio service. Boarding at 1 AM versus boarding at 3:30 AM in Cleveland? Who cares? It won't make much of a difference to ridership.... except that it will make Toledo-Chicago service worse, which is a terrible idea.
Breaking the connections at Chicago is a non-starter. It's not just connections to the West Coast, remember: it's connections to downstate Illinois, Milwaukee, Minneapolis, St. Louis, Kansas City, Denver, etc. By having the overnight train from upstate NY (/ day train from Toledo) arrive in the morning, and by having the train back to the east leave in the evening, you connect to the *entire* midwest corridor network. The number of connections is enormous, and a required overnight hotel stay would break *all* of them.
You can tweak the schedule (and Amtrak does have plans to do so, as noted above), but there are some rules you should follow for the first frequency on the route:
(1) Arrive in Chicago in the morning -- preferably not too early, definitely not too late (connect to all on-time trains)
(2) Depart Chicago in the evening -- preferably not too late, definitely not too early (connect to all on-time trains)
(3) Serve Toledo-Chicago in reasonable hours if possible
(4) Serve upstate NY - Chicago with a reasonable overnight service
(5) Serve upstate NY - NYC with daytime service to fill in the trains which are emptying out as you go east through NY
(6) Forget about Cleveland, you can't serve it properly without a second frequency; serving Cleveland well breaks *everyone* else's service.
Someone has to be served in the middle of the night, and geography tells us that it has to be Cleveland and Erie; any other choice serves fewer city pairs.
Anyway, future improvements which are planned:
(1) The rescheduling of the Capitol Limited and Lake Shore Limited eastbound, as I noted above (more details are in the PIP for the LSL); this should keep the timings into NYC out of the commuter peaks and allow for the removal of delay (although it will hit the Boston commuter traffic contra-peak eastbound).
(2) Englewood Flyover should clear a lot of delay/padding out of the westbound schedules when it's finished, and "Indiana Gateway" should clear out a little more.
(3) Schenectady-Albany double-tracking should remove a lot of delay/padding in both directions
(4) Albany-Poughkeepsie resignalling should remove some delay in both directions
(5) Albany fourth platform should remove a little more delay
The results should allow for better service everywhere except Erie and Cleveland, though Buffalo eastbound arrivals will end up being quite early.
