Shay Locomotive #4 of the Cass Scenic Railroad in West Virginia. Built in 1922. Uses the "Shay" type geared drive system, popular for logging. That line also has both a Climax geared locomotive and a Heisler geared locomotive.

I have been there several times and taken rides on the trains.

Those trains are designed for steep tracks, and yes, even the tracks that they bring tourists on are pretty steep by train track standards.

Steep grades, poorly maintained rails... Shays were known for handling both exceptionally well. If I'm not mistaken, Cass has some of the steepest non-cog-railway grades east of the Rockies.

That is true. If you ever have the opportunity, Cass is a great place to visit. Great camping, white-water rapids and of course, the trains and museums are fantastic.

The trains run almost all day, and the ride is very affordable.
