A split platform or separate platform is a station that has a platform for each track, split onto two or more levels. This configuration allows a narrower station plan horizontally, at the expense of a deeper vertical elevation, because sets of tracks and platforms are stacked above each other. Where two rail lines cross or run parallel for a time, split platforms are sometimes used in a hybrid arrangement that allows for convenient cross-platform interchange between trains running in the same general direction.

A railway platform is an area alongside a railway track providing convenient access to trains. Almost all stations have some form of platform, with larger stations having multiple platforms.
