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 Line2 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.

Authorities warned on 10 August 2020 that Line1 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 and it was expected to conclude in March 2023. 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]
