 The line branches from the Main Western line at Wallerawang and heads north through the townships of Kandos, Rylstone and Mudgee before reaching Gulgong, where there is also a junction to the Sandy Hollow to Gulgong Line.For several years, the section between Kandos and Gulgong was used only for a monthly heritage train service, subject to heavy speed restrictions.The line had previously been closed from 2 March 1992 until 2 September 2000 but was reopened after repairs.
