The narrow gauge lines are connected to the Skarloey Railway. The standard gauge line splits from the North Western Railway's main line at Maron and runs through the Ulfstead Branch Line up to Ulfstead Castle.
The Earl's Dinosaur Park is located on the estate as well.
Stephen and Millie are the only engines working on the railway. However, it is often served by the North Western Railway and the Skarloey Railway, as well as Connor and Caitlin from the Other Railway. Besides tourist operations, the line is also used for maintenance around the estate.
- The railway uses dual gauged track.
