I am not quite sure what attracted me to the ARR. I began looking into it to keep a winter themed layout with the Polar Express. Now after many, many hours of interesting research and reading, I am an ARR fan. I think the allure of the scenery and the respect I have for the people that built and operate a railroad in such rugged conditions has me now.
You won't see any of their cars in service in the lower 48 because of geography. Almost forever, anything is transported from Seattle to Whittier (formerly Seward) via ship or barge. That includes all of their engines and cars.
My favorite resource is John's Alaska Railroad page. Everything is covered. You can click on Rosters to view former and current engines and cars. We tend to overlook the economic dependency on railroads in the lower 48, but nowhere is the survival of a region dependent upon a railroad more obvious than in Alaska.
Brother Love, here's the ARR 1072 with some info. here's engineering drawings
I am currently running a late 1980's train, with two GP38-2's, a mixed freight, and caboose 1087, all Lionel except for two RMT depressed center flatcars with a Bethlehem Steel storage tank load. I like depressed center flats.
Lionel finally updated the SD70MAC for Alaska RR to legacy, which is still the ARR's primary locomotive. They've also added the LionChief plus steamer (wrong road number). So, I think from Lionel, a reissue of the streamliner cars would be nice. Also, some older style flatcars would be good as they are still in use. Could make any load you like, as they do. Also, some intermodals with containers that have correct labeling would be good.They need to lose anything with the eskimo. That paint scheme was only used for months, before they were quickly repainted. I don't care for it. Can you tell?
I , too think the blue\yellow paint scheme is as striking as the UP's armor yellow.
Anyway, it's easy to go on and on for me, so I'll stop now. Enjoy John's page and check out their steamers(Roster\Former locos)
