The Stockinbingal–Parkes railway line (also known as the 'Forbes line') is a railway line in New South Wales, Australia which connects Stockinbingal on the Main South line with Parkes on the Main West line. The line has come to be part of the main route for goods trains travelling between Sydney and the west of NSW and beyond, allowing trains to bypass the steep grades and passenger services on the Blue Mountains section of the Main West line.
