The Oberon Tarana Heritage Railway inc (OTHR) is a volunteer association aiming to reopen the Oberon to Tarana railway line in the Central Tablelands of New South Wales, Australia, and run heritage trains.

[1] The Oberon railway line is a 24-kilometre disused branch railway, which junctions with the Main Western line at Tarana and heads in a southerly direction to the town of Oberon.

Opened on 3 October 1923,[2] the line was lightly constructed, and included steep grades (1 in 25 or 4 %) and tight curves.

[3] It transported local seasonal vegetables, timber and livestock.

[4] The restoration of the line is being undertaken in three stages, per the Railway's 15-year plan from 2020 to 2035:[5] In May 2010, end platform carriages CBA850 and HLF854 were acquired on loan from the New South Wales Rail Transport Museum,[6] as well as railmotor CPH13 from the Canberra Railway Museum.
