Comments on two Alaska Railroad spurs, not mapped in the draft on TM:
In Anchorage, there is an Alaska Railroad depot at the international airport, on a spur from the tracks used for the Coastal Classic and Glacier Discovery routes.
The depot is used by Alaska Railroad-operated charter trains in the high season, taking passengers between the airport and the cruise ship ports in Whittier and Seward (Anchorage doesn't have its own cruise ship port). One of my co-workers took one of those trains from the airport to her cruise ship in Whittier. I'll have to ask my sister and brother-in-law whether they, who just arrived in southeast Alaska by cruise ship, will be taking a train to the airport on their way back home. The airport depot isn't served by other AAR trains, but can be rented out in the off-season for weddings and other events.
In Palmer, there is another AAR depot serving the Alaska State Fair.
AAR has resumed scheduled service there, from Anchorage, after a service lapse after summer 2019.AAR regularly-scheduled passenger trains also make "flag stops" for homes along the tracks (mainly north of Wasilla, and between Whittier and Seward), with no access to the highway network. This may happen in other rail systems in North America and other continents. I suggest these would be best handled with point requests for whoever needs a "flag stop" point.
None of these would be needed for my own .rlist file, since I've never used the Alaska Railroad.
