Mexico City's Metro Line 6 is the red line. Running east-west across the very north of the city, this line opened in 1983. Just 17 of Mexico City's total 390 trains run on Line 6.
With 11 stations, passengers can ride the Metro trains some 11.5 kms. With service terminals at both ends, the total length is almost 14 kms.
All of the stations along Metro Line 6 refer to their areas, and some of the lore, tales, and history of the City. They're how modern-day Mexico City residents map out their own conceptual ideas of the geography of the city.
