In a simple case where two routes with one or two tracks each meet at a junction, a fairly simple layout of tracks suffices to allow trains to transfer from one route to the other. More complicated junctions are needed to permit trains to travel in either direction after joining the new route – for
273:. This applies more as the network density increases. Measures to improve junctions are often more useful than building new railway lines. The capacity of a railway junction can be increased with improved
200:, is a place at which two or more rail routes converge or diverge. The physical connection between the tracks of the two routes (assuming they are of the same gauge) is provided by
289:, and so one track passes over or under another. With more complicated junctions such construction can rapidly become very expensive, especially if space is restricted by

In this latter case, the three points of the triangle may be given different names, for example using points of the compass as well as the name of the overall place.

The installation of junctions into a rail system poses many challenges, including increased maintenance costs, and problems in on-time performance.
