A lot of the trains and artifacts in the big museum are related to the state's mining history. Think silver and the Comstock Lode. This narrow-gauge steam locomotive is the Glenbrook. Built it 1885, it pulled cut timbers from sawmills around Lake Tahoe. I love the colors and detail put into the decorations.
Give yourself more than an hour if you like old trains. If you don’t, I guess it doesn’t much matter.
