The geared steam locomotives that have been built have been for conventional track, relying on the adhesion between wheels and rail.

The Cass Scenic Railroad State Park in West Virginia uses only geared locomotives, and features the largest remaining and last Shay locomotive ever built, the 162-ton former Western Maryland Railway #6. The railroad also owns a Climax locomotive and a Heisler, enabling all three types to be seen.
