A railway station was opened on 1 February 1900 with the first section of the Inverell branch, and operated until 3 December 1985, following the withdrawal of passenger trains on the line. The railway line was progressively closed, with the last section between Moree and Biniguy being listed as out of use in 1994. Today Biniguy is served by Monday to Saturday NSW TrainLink coach services to Grafton and Moree on alternate days. The village formerly had its own post office, general store and public school, however these facilities closed during the 1960s and 70s, with most community services now being provided in Moree.
