Olivos metro station

Olivos is a metro station along Tláhuac Avenue, located in the colonias (Mexican Spanish for "neighborhood") of Ampliación Los Olivos and Granjas San Jerónimo, in the Tláhuac borough, in southeastern Mexico City. Within the system, the station lies between Tezonco and Nopalera metro stations.^[3] The area is serviced by Route 162 of the Red de Transporte de Pasajeros network.^[4]

There are two exits:^[3]

• North: Tláhuac Avenue (between Pino Driveway and Del Panal Street), Ampliación Los Olivos.
• South: Tláhuac Avenue and Olivos Street, Granjas San Jerónimo.

Line 12 of the Mexico City Metro was built by Empresas ICA, in association with Alstom Mexicana and Grupo Carso.^[5] Olivos is an elevated station;^[6] the Olivos–Tezonco interstation is 490 meters (1,610 ft) long, while the Olivos–Nopalera section measures 1,360 meters (4,460 ft).^[7] The station was opened on 30 October 2012, on the first day of the Mixcoac–Tláhuac service.^[8] The facilities are accessible for people with disabilities as there are elevators, tactile pavings and braille signage plates and there is a bicycle parking station.^[3][9] The pictogram depicts an olive branch, as the area was known for olive oil production during the Colonial period.^[3] Originally, the station was projected to be named "Los Olivos".^[10]

From 12 March 2014 to 29 November 2015,^[11][12] Olivos station was closed due to technical and structural faults in the stretch between Atlalilco and Tláhuac.^[13][14]

After the 19 September 2017 earthquake damaged Line 12 tracks, Olivos metro station was temporarily closed,^[15] but three days, later it was reopened and served as the provisional terminal station for one month.^[16][17] According to the official report provided by the Metro system, steel diaphragms were placed in the Tezonco–Olivos section, to provide further support as the beams and headers were affected by the earthquake.^[18] The Olivos–Nopalera overpass was secured^[19] as Column 69 had a flexo-compression failure at the lower end. To repair it, weight was released, epoxy resins were injected, additional reinforcement was placed, and the column was enlarged to its maximum stress zone.^[20]

On 3 May 2021, a section of the elevated line between Olivos and Tezonco metro stations collapsed as a train traversed it. 26 people died and 98 others were injured.^[21] After the 2017 earthquake, the Superior Auditor of the Federation (Auditoría Superior de la Federación) made observations of damage to the collapsed section that were not resolved.^[18]

On 26 August 2022, the line repair team began the dismantling of a girder located 200 m (660 ft) away from the collapse site (in the same interstation section) after finding that its girder could collapse even with the reinforcements that will be installed on the elevated section.^[22]

According to the data provided by the authorities, except for the years when Olivos metro station was closed for several months, commuters have averaged per year between 10,000 and 18,500 daily entrances. In 2019, before the impact of the COVID-19 pandemic on public transport, the station's ridership totaled 6,513,862 passengers,^[23] which represented an increase of 537,987 passengers compared to 2018.^[24] In the same year, Olivos was the 102nd busiest of the system's 195 stations, and it was the line's 7th busiest.^[23]
