It was built above the former Inguarán Avenue (now Congreso de la Unión) in viaduct solution, this makes it the only line without underground section. With only 10 stations, its short length is countervailed with its high connectivity, having transfer with other metro lines in 6 stations: Line 6 at Martín Carrera, Line 5 at Consulado, Line B at Morelos, Line 1 at Candelaria, Line 9 at Jamaica and Line 8 at Santa Anita . However, it is also the line with the least passengers in the entire system, having only 30,516,924 passengers throughout 2016. .
The line is also characterized by its above-ground architecture, having all of its station facilities elevated or in massive buildings present in both sides of the street. A side effect of this is having long passageways with connecting lines, generally unused or empty sections in stations, closed passageways and other features, all due to its low ridership. Also, trains in Line 4 have been shortened from its original configuration of nine cars to only six..
The first stretch of Line 4 was inaugurated on August 29, 1981, from Martín Carrera station to Candelaria station. Line 4 was the first line to feature an elevated section, built over Avenida H. Congreso de la Unión. Lines 9, B and 12 would later also have elevated sections.
The second stage of the line was opened for service on May 26, 1982, with four new stations, going from Candelaria to Santa Anita.
Upon completion of the line, it had only two transfer stations: Candelaria with Line 1 and Consulado with Line 5. Transfer to Line 6 at Martín Carrera would open in 1986, to Line 9 at Jamaica in 1987, to Line 8 at Santa Anita in 1995 and to Line B at Morelos in 1999.
There were plans to extend the line north towards Ecatepec de Morelos, but, as of 2018, no extension has been built nor any plans have been confirmed.
