# Turin Metropolitan Railway Service

The Turin Metropolitan Railway Service (Italian: Servizio Ferroviario Metropolitano), simply known as SFM, is a commuter rail system serving the metropolitan area of Turin, Italy. The system comprises 8 lines operated by Gruppo Torinese Trasporti and Trenitalia, serving 93 stations.
The core of the system is the passante ferroviario, a tunnel running 8 km through the city from north to south at a maximum depth of 18 meters. The tunnel allows passengers to travel from Torino Stura station to Torino Lingotto station in 15 minutes.

## History

* 1999: The project was born from a proposal by the Piedmont Region to make the best use of the railway infrastructure works being carried out in the city. (the "railway bypass").
* 2006: The Turin Metropolitan Mobility Agency resumes planning after the future SFM lines have been transferred to the management of the Agency itself.
* 4 December 2012: The service is officially presented at the Mole Antonelliana in the presence of the President and Councillor for Transport of the Piedmont Region, the Mayor of Turin representing the 60 municipalities reached by the SFM and the top management of Ferrovie dello Stato and GTT.
* 9 December 2012: Activation with five metropolitan railway lines, 1, 2, 3, 4, A, following the modernization of the Turin Passante Ferroviario (quadrupling of the tracks, burying and construction of intermediate stops). The service is based on a daily traffic of 256 trains per day through 75 stations.
* February 1, 2013: The official portal of the service is born.
* June 9, 2013: The SFM 7 (Turin-Fossano) and SFM B (Cavallermaggiore-Bra-Alba) lines are established . The service now covers 85 stations and 326 trains.

### Infrastructure

The major intervention required by SFM is the construction of the railway underpass, which replaced the historic line on the same surface route, and was activated in December 2012. The reconnection between the SFM A line and the railway underpass is planned, having been cut off at Turin Dora Station by the lowering of the track level of the TO-MI railway by 14 m. In addition to this infrastructure, two new stations will be built along the new connecting route under Corso Grosseto and the current stations will be redeveloped.
A technological intervention is planned in the bypass to allow a 4-minute spacing between trains.

### Tickets

Tickets for SFM are integrated with the GTT urban service , meaning you can use any public transport (bus, tram, metro and railways) within the urban area of Turin for the entire validity of the ticket. There are 3 types of tickets available that can be purchased at all authorised GTT retailers, newsagents and tobacconists:
Integrated A (cost €3.50) urban area and first belt. Valid for 100 minutes on the GTT urban and suburban network, on the metro (1 journey only) and on the Trenitalia and GTT railway lines. Integrated B (cost €4.00) urban area, first and second belt. Valid for 120 minutes on the GTT urban and suburban network, on the metro (1 journey only), on the Trenitalia and GTT railway lines and on the extra-urban bus lines managed by Extra.To.
