The Flemington Racecourse line is a railway line in Melbourne, Victoria. Operated by Metro Trains Melbourne, it is the city's shortest metropolitan railway line at 7.8 kilometres. The line runs from Flinders Street station in central Melbourne through the Craigieburn line and branching off at Newmarket where it only serves only just two stations, Showgrounds and Flemington Racecourse, the is only being used during the Melbourne cup, oaks day and the Royal Melbourne show and any other events
the line was constructed in 1861 by the Melbourne and Essendon railway company the operation was barely profitable and, in early 1864, the company asked the Government of Victoria to buy the railway. The request was refused and the line was closed in July 1864. For the next three years, determined efforts were made to get the government to change its decision. In August 1867, the government paid £22,500 for the company's assets, and they became part of Victorian Railways. The racecourse branch was reopened in November 1867, and the section from Newmarket to Essendon was reopened in January 1871
