Due to the relative shortness of the branch, the main use of the line was for grain haulage rather than passengers.
In 1927, a rail-motor coach replaced steam locomotives for passenger transport. The "Tin Hare", as the coach was affectionately known, provided a daily return service on weekdays between Cowra and Eugowra. With improving road transport links, demand for passenger services on the line gradually decreased. In the years leading up to the service's cessation on 10 August 1974, the few passengers that used the service had been carried in the brake carriage of the regular grain service.[1][4]
Freight services continued into the 1990s. A washout near Eugowra in 1991 resulted in the line being truncated at Trajere. The entire line was closed by the end of the year.[1] The Lachlan Valley Railway operated a tourist railway on the line from 1994. Floods in 2001 damaged a bridge at Cucumber Creek, closing the line permanently. As of 2014, there are no plans to reopen the branch.[1]
