The border between the two municipalities runs along the Torrente Ramogna stream, a short distance to the south and west of the station.

Since 1990, Locarno station has been divided into two distinct components, each served by a separately operated railway.

At surface level, there is a standard gauge station, operated by the Swiss Federal Railways (SBB CFF FFS).

Underground, there is another terminal station, Locarno FART, for the metre gauge Domodossola–Locarno railway, an international rail link operated in Switzerland by the Regional Bus and Rail Company of Canton Ticino (Italian: Ferrovie Autolinee Regionali Ticinesi, or FART).

Additionally, the two railway lines' goods yards were removed, and the underground station constructed in their place.
