Three of their engines are lettered for the Glenwood, South Park & Pacific.
Consolidation number 13, while modeled after a South Pacific Coast locomotive, is labeled for the GSP&P and carries a herald reminiscent of the C&S columbine logo.
Below is a video of GSP&P 13
Another engine on the roster is GSP&P #5, a mogul.
Here is a video of #5 in action.
The third locomotive labeled for the GSP&P is number 7, a Shay. Is it me, or is that Jeff Badger, chief mechanical officer of the Georgetown Loop in the photo?
