If there are others, I would love to know of them. Oh, yeah, Winter Park?
Old Orchard beach is a seasonal stop only served May through October. It is also not served by the first Eastbound train of the day (680 or 690).Old Orchard Beach on the Downeaster is seasonal in nature, if not in terms of actual service.
The Williams AZ stop could have been convenient for connecting to the Grand Canyon RR that would take you right to the South Rim where the hotels are very close by. The problem as I see it was that the timing of the Amtrak and Grand Canyon RR didn't coincide. The Williams SWC stop was also too far from downtown Williams and had no services or even a shelter. If you wish to visit the Grand Canyon by train today you can arrive at Flagstaff, AZ late in the evening, walk two or three blocks to the Marriott Spring Hills Suites, spend an overnight and have Enterprise Car Rental deliver an auto to you in the morning. That how we did it.Williams Jct., AZ was an off and on stop. First established in 1960 when the transcon was rerouted north of Williams, it closed when the Phoenix and Grand Canyon trains were discontinued in 1969.
Amtrak operated a stop 1999-2017 as a connection to the Grand Canyon RR. The middle of the night times and the need to operate a shuttle into Williams sunk it.
On the Wolverine, there was a Greenfield Village stop that was only served for tour groups. This went away when they opened the new Dearborn station, which has a bridge connecting to Henry Ford/Greenfield Village (though I’ve heard that is usually locked…)
Which is interesting because the Pacific Surfliner (for some trains) recently added the Metrolink stops of Burbank-Downtown (BBK) and Northridge (NRG) on the Ventura County Line.For a while, some Amtrak trains made stops at Coaster commuter rail stations (Sorrento Valley, Encinitas, Carlsbad Poinsettia and Village) on some Pacific Surfliner trains, in conjunction with cross-honoring tickets. This was to offer additional train options to Coaster passengers. After a couple years they dropped the additional stops, though they still cross-honor some Coaster tickets on Surfliner trains. I think there were also some Metrolink stops in Orange County the Surfliner used to stop at and does no more as well…
