They are all powered by steam from two large boilers, nicknamed Pat and Rich, after two long-time museum volunteers who maintain and operate them.

There are six operational steam traction engines on the grounds, with a 1913 Buffalo-Pitts steamroller and a 1909 20 horsepower Case undergoing restoration.

Also located on museum grounds is the Short Track Model Railroad Club, featuring an NTrak model railroad with trains traveling through more than 40 modules, including a drive-in movie theater, a fairgrounds, farms, towns, and a coal mine and other scenes.

Their Donner Pass, N-scale, model railroad exhibit shows the Southern Pacific crossing of the Sierra Mountains between Colfax, CA and West Reno, NV.

The Sawmill is run by a D-3000 Cat diesel engine, Hawthorne Machinery in San Diego provided the cylinder liners.

The Sawmill was re-assembled and improved following a donation from the Pederson Brothers who had operated it in the Big Bear area years ago.
