My wife and I took the Alaska Railroad from Anchorage to Seward for the day, leaving early in the morning and getting back around 10 pm. Even though it was cloudy for most of the trip, the scenery in the Kenai Peninsula is unbelievably unspoiled and majestic. Glaciers, flora, fauna, rivers, tunnels, bridges--it's all there. The ride is about 3.5 hours or so one way, but it's the only mode of transportation through part of the Peninsula, as the road to Seward takes a different route.
The train itself was average compared to other trains I've ridden. We didn't upgrade to the double decker, but ours had large windows that permitted plenty of photo ops. A great day trip overall.
