There was a standard gauge climax pulled out of a swamp in Romayor, TX that was built as narrow gauge
Romayor Climax
Before it moved down south and standard gauged it was in use at a handful of private mining railroads in the Copper Country of Michigan, original thought to have been bought for a sandstone quarry on the eastern edge of the Keweenaw peninsula before being transferred to the Mohawk & Traverse Bay railroad which connected the Mohawk and Wolverine mines to their stamp mills at Gay, MI around the turn of the century. The locomotive was then sold to the Phoenix Mine and ran on their secluded Phoenix Mine & Gratiot River RR in 1902 after the M&TB RR standard gauged. Later the site was standard gauged when the Keweenaw Central RR came in and the last of the Phoenix 3' gauge was pulled out around 1908
Only few photos exist of it when it was still in use
