The Umgeni Steam Railway runs on a 3ft, 6 inch (1067mm) gauge heritage railway line. The route follows part of the Durban to Pietermaritzburg mainline opened in 1880, and traverses some of the steepest railway gradients in South Africa. The trip includes a 53-metre-long tunnel at Drummond, built in 1878 which is quite possibly the oldest tunnel still in use in South Africa today. “Wesley” is a Class 19D locomotive which is used for the monthly excursions and was built by Borsig Locomotiv Werke, Hennigsdorf in 1938. The coaches vary in age – some were built as long ago as 1908, most in the 1930s and the youngest was built in 1953.
The Umgeni Steam Railway is a non-profit company run entirely by volunteers who maintain and operate the trains as well as the museum and archives. The organisation is dedicated to preserving the heritage of railways in South Africa and they have in their care a sizable array of historically significant locomotives, coaches and various goods wagons.
