Newly released film of the Stronach-Dutton system in the 1920's
A unique railway system that combined the high tractive effort from rubber road wheels with low rolling resistance of a railway.
This had many advantages such as tight curves (down to 35ft) steep gradients (1:12) very light construction of the track with only light earthworks. It was very economical to build and operate and required only one man to operate it.
The Road-Rail tractor could use a conventional road lorry converted to have its front wheels jacked up over a front bogie and had its rear driving wheels each side of a narrow gauge track. The road wheels transmitted the pulling power to the ground and the train was hauled on the rails.
The system was tried and used in many countries including England, Scotland, Spain, Morocco, Palestine, Union of South Africa, Uganda, Australia, Tasmania, India.

The Stronachie Distillery to Meikle Sleggie Farm Road-rail replaced a steam traction engine and road wagons due to damage to the poor lanes. The road-rail ran over some tough terrain where gradients of 1 in 10 were frequent and 1 in 7 was the steepest encountered. A sprag was trailed at the rear of the last wagon when going up hill for safety purposes.
