Split platform

A split platform, stacked 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 (or footprint) horizontally, at the expense of a deeper (or higher) 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.

If a road was too narrow to allow the construction of side-by-side tunnels, they would be aligned one above the other, so that a number of stations have platforms at different levels. It is also sometimes used if the line branches from the station, so diverting tunnels or tracks do not intersect each other. ==Examples== ==Notes and references== ===Notes=== ===References=== ==Bibliography==
