The Warrnambool railway line (also known as the South West line, formerly known as the Port Fairy railway line) is a railway serving the south west of Victoria, Australia. Running from the western Melbourne suburb of Newport through the cities of Geelong and Warrnambool, the line once terminated at the coastal town of Port Fairy before being truncated to Dennington (just west of Warrnambool). This closed section of line has been converted into the 37 km long Port Fairy to Warrnambool Rail Trail. The line continues to see both passenger and freight services today.
