The line runs from Flinders Street station in central Melbourne to Frankston station in the south-east, serving 28 stations via South Yarra, Caulfield, Moorabbin, and Mordialloc. The line continues to Stony Point on the non-electrified Stony Point line. The line operates for approximately 20 hours a day (from approximately 4:00 am to around 11:30 pm) with 24 hour service available on Friday and Saturday nights. During peak hour, headways of up to 5 to 10 minutes are operated with services every 10–20 minutes during off-peak hours. Trains on the Frankston line run with a two three-car formations of Comeng, Siemens Nexas, and X'Trapolis 100 trainsets. Sections of the Frankston line opened as early as 1881, with the line fully extended to Frankston in 1882. A limited number of stations were first opened, with infill stations progressively opened between 1881 and 2017. The line was built to connect Melbourne with the rural towns of Caulfield, Moorabbin, and Frankston, amongst others. Significant growth has occurred since opening, with a plan to extend the Frankston line along part of the Stony Point line to Baxter. Since the 2010s, due to the heavily utilised infrastructure of the Frankston line, significant improvements and upgrades have been made. Different packages of works have upgraded the corridor to replace sleepers, upgrading signalling technology, the introduction of new rolling stock, and the removal of all level crossings. In 1881, the Frankston line began operations by the Victorian Railways on a single tracked line from Caulfield to Mordialloc. Mordialloc station was officially opened on 19 December 1881 by Sir Thomas Bent, who was the Minister of Railways, and later becoming the Premier of Victoria between 1904 and 1909. The first train to arrive at Mordialloc was a special service from Princes Bridge, which collected school children from the Brighton area.
