Alaska Railroad Subdivision, Port of Whittier - Anchorage Railyard. This Subdivision should also include the EMD SD70MAC & the EMD GP40-2 Locomotives. Also it would have Freight & passenger services.
Sounds like an interesting idea. Though, I would rather see something Canadian added since there is a crapload of US routes already.
I can agree with you, we should get Canadian Pacific Selkirk Subdivision that goes up the Rocky Mountains and through the spiral tunnel. But an Alaska Railroad Subdivision would be awesome as well.
