Line 1 of the Mexico City Metro was built by Ingeniería de Sistemas de Transportes Metropolitano, Electrometro, and Cometro, the latter being a subsidiary of
Empresas ICA. Its first section, where Zaragoza metro station is located, was inaugurated on 4 September 1969, operating from Zaragoza to
Chapultepec station, and opened to the general public the following day. The line's
workshops are found in the tunnel following Zaragoza. On 22 August 1984, Pantitlán station was opened eastward to connect Lines 1 and
5. The workshop's location indirectly benefited the line's operations as it allowed trains to depart to either station every 90 seconds. The station was closed on 11 July 2022 for modernization work on the tunnel and technical equipment of the line. After fifteen months of renovations, authorities reopened Zaragoza station on 29 October 2023.
Excélsior reported in July 2024 that all the modernized stations had leaks of varying dimensions, including water filtration on the train boarding platforms at Zaragoza station. Authorities had previously stated that these leaks would be sealed during the 2022 modernization works.
Landmarks The Instituto de Capacitacion y Desarrollo Zaragoza, located near the station, trains system personnel using full-scale replicas and models of the facilities and equipment. Known as Expometro, it is open to the general public for guided tours. == Ridership ==
