Here's an overview of part of the SRC shop. Beyond it, the shiny wheels you see are the driver centers for the 4-8-8-4 "Big Boy" currently being restored by the Union Pacific. All 12 of its wheel sets are at the Strasburg for bearing and other work.

In the foreground is a narrow gauge 4-6-0 owned by the Colorado Railroad Museum, originally built for the Florence & Cripple Creek. It's undergoing a long-term heavy overhaul.
