Infrastructure
The Frankston railway line shares four tracks with the line to Dandenong and beyond from near Richmond to Caulfield, running next to the Sandringham line as far as South Yarra.
From Caulfield, the Frankston line has three tracks to Moorabbin. The centre track is signalled for bidirectional operation, allowing for express trains overtaking stopping trains in the peak direction. From Moorabbin to Frankston the line is double track.
Power signalling is provided throughout, and intermediate terminating facilities are provided at Moorabbin, Cheltenham, Mordialloc, and Carrum. Stabling facilities for suburban trains are provided at Mordialloc, Carrum, and Frankston.
