Glenreagh Mountain Railway, known as the GMR, was established in 1989 as a heritage tourist railway at Glenreagh, near Coffs Harbour, New South Wales, Australia. GMR's objective is to restore and operate a heritage tourist railway on the Glenreagh to Ulong section of the Glenreagh to Dorrigo railway line.
GMR is a non-profit, community-based organisation run entirely by volunteers, and has an authority to raise funds under the Charitable Collections Act.
The GMR acquired the 35-kilometre section to Ulong in 1999 from the then State Rail Authority of New South Wales, and is currently restoring this section of line as well as rolling stock, to enable the heritage tourist railway to operate.
GMR's current rolling stock includes steam locomotive Z19 class 1919, 4-wheel watergin L568, TAM sleeping car, 2 heritage end-platform cars, S trucks, ex-Sydney interurban cars ("U-boats") and numerous trikes and track maintenance vehicles.
As of December 2005, GMR has completed trackwork to safe working standards for train operation from Glenreagh West Depot 3.5 km west to Talawajah Creek. Steam train operations were scheduled one weekend a month subject to fire bans. Recently, operations have ceased while GMR works to fulfil its obligations under the Rail Safety Act.
