Mexico City Metro Line 4 is the fourth line of Mexico City Metro.[1][2] The line color is aqua blue and it runs from north to south of the city crossing the city center by its easternmost area.

General information

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.[3] .

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.[4].
