San Sebastián Metro

The meter-gauge line opened on December 5, 1912 between San Sebastián with Irun. It was extended to Hendaye the following year.^[5] The network was subsequently owned by FEVE, the Spanish narrow-gauge railway company, until it was transferred to the Basque Government in the 1970s. In the early 1980s, it was integrated into EuskoTren, along with other narrow-gauge lines in the Basque Country.

Since the 2010s, the line has been gradually upgraded towards rapid transit standards. In 2012, together with the opening of a new tunnel between Loiola and Herrera, it was announced that the line would be renamed to Metro Donostialdea. This branding, however, has since been abandoned.^[3] In 2015, a branch was opened from Herrera to Altza. This branch will be part of the new alignment between Herrera and Galtzaraborda.^[6][7]

A 4.2 km (2.6 mi) underground loop through the city centre was originally planned to open in 2022,^[8][9] but is now (as of 2023^[update]) scheduled for 2025 or early 2026.^[10] This new tunnel will have three stations: Benta Berri, Centro-La Concha and Easo;^[11] the last one of which will substitute the current Amara terminus. When the tunnel is completed, the need to reverse at Amara will disappear.^[12]

The works on the new Altza-Galtzaraborda stretch began in February 2022, with completion scheduled for 2027.^[13] This new alignment will simplify operations by absorbing the Altza branch into the main line. When completed, the line will be double-tracked between Errekalde and Galtzaraborda.^{[citation needed]}

There are two numbered lines: E2 and E5. Line E5 runs from Amara to Altza every 15 minutes on weekdays, and every 30 minutes during most of the weekend. Line E2 has two services: one from Lasarte-Oria to Irun, and another one from Lasarte-Oria to Hendaia; each running every 30 minutes during weekdays. The Irun to Lasarte-Oria service is reduced on weekends to a twice-hourly service from Irun to Amara on Saturday afternoons.^[14] Additionally, trains running on the Bilbao-San Sebastián line call at all the stations between Errekalde and Amara.^[15]

Due to the existence of various overlapping services, headways vary depending on the time of the day and location. Since 2012, with the opening of the new Loiola-Herrera tunnel, there is a train every 7.5 minutes between Amara and Herrera.^[16] With the opening of the tunnel through the city center, it will be possible to offer regular headways in a longer stretch of the line.^{[citation needed]}

The following table shows regular weekday service patterns. The first trains in the morning and the last in the evening make shorter trips.^[14]

The line shares rolling stock with the rest of the Euskotren Trena network. Currently, 900 series trains are used.^[17][18] In the past, 200, 300 and 3500 series trains were used.^[19]
