The city of Palma (Majorca) has opened its metro in 2007. It runs on metre-gauge tracks to ensure compatibility with the railway line to Inca. Since 2013, this route is also used by metro trains until Marratxí (line M2) after the electrification of the railway line. The ridership on the main line M1 is rather small outside the lectures at the university, this is why the metro runs only every 30 minutes during off-peak times. On Sundays and bank holidays, the metro is even out of service.
The metro is operated by SFM (Serveis Ferroviaris de Mallorca, this company is also the operator of the railway lines to Manacor and Sa Pobla) under the authority of → TIB (Transports de les Illes Balears)
