Because I was so impressed with the Alaska RR, I decided to do a train for our club in the Alaska RR. I bought a Kato SD70 and some of the Spectrum McKinley cars. There are decals available for the Alaska, but none for the Princess cars. Princess gave me permission to do decals with their loco so, I had a few made up. I am enclosing a couple of pictures that you might be interested in seeing. One is of an Alaska RR car and the other is my first attempt at a Princess car. While the McKinley car is not exactly the same and has no skirt, it is close enough.
Update [4/22/08]: I finished my Alaska passenger train and ran it on the Treasure Coast Model Railroad in Port St Lucie FL. I am enclosing a picture of the Alaska RR full Dome car I did and also a picture of the full train on the TCMRR. Also enclosed is a picture of both the Alaska SD70M and the Florida East Coast SD70M. Thought you might be interested in seeing them together.
