 4 Shay locomotives were imported from the Lima Locomotive Works in the USA.Although rather slow, their unique build which uses crankshafts to propel the wheels made them very suitable, and if a train had to stop on a steep uphill grade, the train could easily start again and keep moving.After the line closed, its route was used by part of the pipeline that carried refined petroleum from the Glen Davis Shale Oil Works to Newnes Junction.
