The Sandringham railway line is a suburban railway line in Melbourne, Australia. It branches from other southeastern suburban rail lines (inferred as the "Caulfield group") at South Yarra station. It serves the City of Bayside, and small sections cover the Cities of Glen Eira, Port Phillip, Stonnington, and Yarra. Various sections of the track opened between 1857 and 1859, and in May 1919, the whole line was electrified.
