It is an elevated station with two side platforms, served by Line12 (the Golden Line), between Nopalera and Tlaltenco stations. The station's pictogram features the glyph of Santiago Zapotitlán, which shows a toothed sapote tree with three branches. The station was opened on 30October 2012, on the first day of service between Tláhuac and Mixcoac stations.
The station facilities are accessible for people with disabilities and there is a bicycle parking station. In 2019, the station had an average daily ridership of 13,683 passengers, making it the 13thbusiest station on the line. Since it was opened, Zapotitlán station has had multiple incidents, including a 20-month closure in 2014 due to structural faults found in the elevated section of the line, a closure caused by the 19September 2017 earthquake, and the subsequent collapse of the track near Olivos station in 2021.
Location and station layout
Zapotitlán is a metro station along Tláhuac Avenue, located in the town of Santiago Zapotitlán[es] and the colonia (Mexican Spanish for "neighborhood") of Conchita Zapotitlán, in the Tláhuac borough, in southeastern Mexico City. Within the system, the station lies between Nopalera and Tlaltenco stations.[3] The facilities are accessible for people with disabilities and there is a bicycle parking station.[3][4]
There are two exits: the northern one on the corner of Tláhuac Avenue and Cesáreo Castro Street, in the town of Santiago Zapotitlán, and the second in the opposite side of Tláhuac Avenue, on the corner of Emilio Laurent Street, in the colonia of Conchita Zapotitlán.[3] Zapotitlán station has two levels: the station's platforms and the access lobby.[5] The area is serviced by Routes162 and 162-D of the Red de Transporte de Pasajeros network.[6]
History and construction
Support columns, 2010
Line12 of the Mexico City Metro was built by Empresas ICA, in association with Alstom Mexicana and Grupo Carso.[7] Zapotitlán is an elevated station;[8] the Zapotitlán–Nopalera interstation is 1,276m (4,186ft) long,[9] while the Zapotitlán–Tlaltenco section goes from overground to the street level,[8] and measures 1,115m (3,658ft).[9]
The station was opened on 30October 2012, on the first day of the Mixcoac–Tláhuac service.[10] Zapotitlán station is named after the town of Santiago Zapotitlán and its pictogram depicts the glyph of the town, which depicts an indented sapote tree with three branches. The tree is toothed, a reference to the Nahuatl word Tlantli (meaning 'tooth'), which is represented in the name of the station by the suffix -tlan.[3]
Incidents
The original location was opposed by local residents and it ended up being changed.[11][12] Since 2010, the Superior Auditor of the Federation has audited Line 12 several times and has reported several faults, like cracks and detachments along the line, including some at the Nopalera–Zapotitlán–Tlaltenco overpass.[13][14]
From 12March 2014 to 29November 2015,[15][16] Zapotitlán was closed due to technical and structural faults in the stretch Atlalilco–Tláhuac.[17][18] After the 19September 2017 earthquake damaged Line12 tracks, Zapotitlán remained closed until 30October 2017.[19][20] In the zone, the earthquake derailed two trains: one in the Zapotitlán–Tlaltenco overpass and the other one on the opposite section;[21] the latter damaged the track's seismic jacketing protection.[22] On 3May 2021, the station was closed after a portion of Line 12's elevated railway collapsed near Olivos station.[23]
The system identified Curves 11 and 12 along Tláhuac Avenue as a railroad wear zone.
Between Zapotitlán and Nopalera stations there are two sharp curves close to each other; the system marks them as Curves11 and 12. Curve11 has a radius of 200m (660ft) while Curve12 has a radius of 201.9m (662ft)—both are the tightest of the overpass.[24] According to the Metro union leader, when there are sharp curves, the trains wear out the rails and wheels, causing them to clatter and damage structures such as girders and columns.[21] After the 2017 earthquake, a girder in the section was reinforced with a diagonally-reinforced beam.[25] The line uses FE-10 steel-wheeled trains by Construcciones y Auxiliar de Ferrocarriles. They have a length of 140m (460ft) and a width of 280cm (110in).[26][27] According to the former director of the system, Joel Ortega, trains do not exit a curve when they are already on the next one, and the maximum speed for taking them was adjusted to 25km/h (16mph) for safe train travel but the speed wears and tears on the tracks and wheels. He also said that damage to the tracks had been reported since 2012 and that 900m (3,000ft) of track had been replaced within a month of its inauguration.[28]
Ridership
According to the data provided by the authorities, except for the years when the station was closed for several months, commuters have averaged per year between 10,800 and 13,700 daily entrances. In 2019, before the impact of the COVID-19 pandemic on public transport, the station's ridership totaled 4,994,118 passengers,[29] which represented an increase of 379,217 passengers compared to 2018.[30] In the same year, Zapotitlán was the 130thbusiest of the system's 195stations, and it was the line's 13thbusiest.[29]
