A great portion of the Urban Railway Lines lies underground, in tunnels. Tunnels are like huge dark mazes. When navigating thru a maze, we usually rely on maps. Track diagrams are a type of map that clearly and accurately tells us connection between tracks. They may also include signals and other equipments along the tracks. We have made several simple track diagrams on various Mass Transit Railway lines. Each single track diagram deals with one of these lines only.

IMPORTANT: PLEASE BE ACKNOWLEDGED THAT ACCESS OF ANY KIND TO ANY PORTION OF MTR TRACKS IS VERY DANGEROUS AND ILLEGAL. TREAT THESE TRACK DIAGRAMS WE PROVIDE BELOW AS AN ADDITIONAL REFERENCE ONLY.
