 In 1966, the railway was rebuilt on a new alignment and extended.The line saw considerable success in the late 1960s, and another steam locomotive, "Elin", arrived, although it was too heavy for the lightly laid track which limited axle loadings to approximately 2.5 tonnes.Trains operated push-pull for many years, but an accident resulted in the Railway Inspectorate requiring the installation of run-round loops, so that the locomotive would always be at the head of the train, and air brakes.
