The narrow-gauge railway from Moldovita was built by a sawmill owner from Munich, Louis Ortieb, and put into use in 1888 for the transport of wood from the forest to the sawmill.
In 1909, the line was taken over from the church fund, which changed the gauge of the line from 800 millimeters to the standardized gauge of 760 millimeters. Initially, the mocănița route was 23.9 kilometers long, from Moldovița to Roșoșa, but over the years, many more variants were built and the whole system arrived in 1987 with the establishment of the Râșcovei – Râșca dħrăta + Arsuri section at one length of 73 kilometers.
The line from Moldovita was used until 2001 for transporting wood. Since July 2005, the line is managed by the Association for the Preservation of Narrow Lines in Romania. Currently, the line is 10.5 kilometers long.
