“Great experience. Possibly not for everybody.”
The Lake Superior Museum is housed in the historic Duluth Depot, which allows them to not only show the rolling stock easily, but to provide historical context, which is pretty cool.
For me, the centerpiece of the train exhibit is the impossibly huge Mallet No. 227 engine, which is one of the most powerful steam locomotives ever built. An absurd 128 feet long, and shiny black, it's truly astonishing. Even cooler: climb aboard! Sitting in the engineer's seat, it's like driving a car where the hood is a half-block long, and impossible to see over.
There are lots of other locomotives, and other cars, including cabooses, which are particularly interesting. Many of them are open to walk through.
A warning about the walking: these trains were all built before the ADA, and many are completely inaccessible to people with limited mobility. I don't fault the museum, since the inside of a diesel-electric locomotive is very cramped, and the climb up to the gondola of the caboose was designed for railwaymen in reasonable physical shape.
Also, I can imagine that not everybody is into this kind of history. But if you are remotely interested in historical technology, or even just in enormous powerful machines, you'll want to spend two or three hours here.
