rMMnDS (Spanish) is a homebrew application that can calculate the shortest route from one point to another for the Madrid Metro (Metro System). It implements the algorithms for the shortest route between two subway stations, and allow you to search a station by name.
In the latest version, it also has the Cercanías Madrid network available. Calculations can be made within each individual network, or you can perform search between different networks (which takes into account of both the number of stops and transfers between 2 stations).
