CF&I Mine Rescue Car No. 1 is believed to be the only remaining wooden Mine Rescue Car in the United States. Between 1923 and 1941 this converted Pullman style railroad car was used as a training vehicle for mine emergency procedures and first-aid triage techniques. After retiring the car, it was used as a company office in the steel mill. Exhibits inside the car relate to mine rescue and mine safety. Funding was provided through grants from the Colorado State Historical Fund and heroic fundraising efforts by the Pueblo County Historical Society.

The train car is a featured artifact in the Steelworks Park, now open!
