Chapultepec station during the first day of operations after the inauguration.

The first section of Line 1 was opened on 4 September 1969 as part of Mexico City Metro's first construction stage, it was inaugurated by Gustavo Díaz Ordaz, President of Mexico from 1964 to 1970, and Alfonso Corona del Rosal, Regent of the Federal District Department.[3] The inauguration ceremony took place at the Insurgentes station.[4]

The next day the line was opened to the public. To the original route (Chapultepec–Zaragoza) a new station, Juanacatlán, was added to the west on 11 April 1970, and the first correspondencia (a transfer station) became functional on 1 August 1970 when Line 2 was opened. The two westernmost stations Tacubaya and current terminal Observatorio were inaugurated on 20 November 1970 and 10 June 1972 respectively.

Station Pantitlán was opened on 22 August 1984 as the eastern terminal during a fourth and final expansion. All twenty stations have operated since then, running a total track length of 18.83 km (11.70 mi), of which 16.65 km (10.35 mi) are passenger track. The 1 is the only line in the network that is fully underground except for some surface track in Observatorio used for maintenance.

As of 2020, an extension of Line 12 is under construction, this stretch will connect Line 12 with Line 1 at the Observatorio station.[2]

Temporary platform installed at Balderas station

Authorities warned on 10 August 2020 that Line 1 is in danger of a major fire due to an aging electrical system that is in need of major improvements. Lines 1, 2, and 3 report an average of 2.5 electrical failures daily.[5] As a result, the line started undergo renovations that require its closure. The first closure was from Pantitlán to Salto de Agua stations, starting on 11 July 2022 with March 2023 being the expected completion date. The second closure was expected to start in March 2023 from Balderas to Observatorio stations and was expected to conclude in August 2023. During both periods, all railway elements will be replaced with modern material, the wiring will be replaced, damage due to leaks and cracks will be repaired, stations that are not yet modernized will be updated, and accessibility will be added to stations that lack it.[6][7]

In April 2023, Siemens Mobility claimed that they would install CBTC on Line 1.[8] On October 29, 2023, the modernized section of Line 1 was inaugurated.[9] Salto del Agua and Balderas stations was reopened on September 13, 2024.[10] The second stage is expected to begin on 9 November 2023.[11]

On November 16, 2025, the Observatorio - Chapultepec section of metro line 1 was reopened, thus completing its full modernization.[12] The modernization, which included CBTC installation, is expected to increase capacity by 15%.[13]
