In total, the track climbs over 700 feet along its thirteen and a half mile length, including turning a complete spiral at Dduallt, purely in order to gain height. For a lot of its distance, the railway clings to the edge of the mountainside but towards the top, it passes through a number of short tunnels.
The railway is mainly single track, but the stations at Minffordd, Tan-y-Bwlch and Tan-y-grisiau allow up and down trains to pass. Tan-y-Bwych is also a water stop for up trains.
