Regional-Metropolitan Railway services

The Suburban Railway Service ( "S" Lines, a service similar to the French RER and German S-Bahn), composed of eight suburban lines and ten more scheduled for 2008, connects the "Greater Milan" to cities such as Como and Varese. The Regional Railway Service ("R"), instead, links Milan with the rest of Lombardy and the national railway system. The "Passante ferroviario" is an underground railway serving a couple of "S" lines and is very much like another subway line (and is even marked as such on subway maps), except that it is connected to LeNord and Trenitalia suburban networks.
