Mexico City Metro Line B

Line B under construction over Avenida Central in Ciudad Nezahualcóyotl.

Line B was planned as a feeder line that would connect Mexico City to the adjacent municipalities of the State of Mexico, such as Ecatepec de Morelos and Ciudad Nezahualcóyotl, therefore, instead of using the same numbering system as with the other metro lines, the line was named as Line B, same as in Line A, which connects Mexico City with the municipality of La Paz, also in the State of Mexico.

Line B was conceived in the early 1990s and was to originally named as Line 10. The 1994 Mexican peso crisis affected the construction of the line on its first stages as well as opposition from the citizens, specially those living in Santa María la Ribera, who claimed that Line B construction affected their houses, with damages such as sinking and breakage.[4]

The first stretch of the line, from Buenavista to Villa de Aragón, was inaugurated on 15 December 1999 by Ernesto Zedillo, President of Mexico from 1994 to 2000, and Rosario Robles, Head of Government of the Federal District from 1991 to 2000. The second section, from Villa de Aragón to Ciudad Azteca, was opened on 30 November 2000, six years after it was planned.[4]

An extension for Line B is planned, adding two more stations to expand the line westbound towards Colegio Militar, where line B would connect with Line 2.[5]

Upon its completion, Line B became the first line in the Mexico City Metro network to feature the three type of stations: elevated, surface and underground.[3]

• 15 December 1999: from Villa de Aragón to Buenavista
• 30 November 2000: from Ciudad Azteca to Nezahualcóyotl

• Alstom MP-68: 1999–present

Currently, out of the 390 trains in the Mexico City Metro network, 36 are in service in Line B.[6]

The following table shows each of Line 12 stations total and average daily ridership during 2019.[1]

Line B passes near several places of interest:

• Plaza Garibaldi, a square known as Mexico City's home of mariachi music where mariachi bands can be found playing or soliciting gigs from visitors.
• Historic center of Mexico City

On its route, Line B passes through some places known for their levels of crime including Ecatepec de Morelos, Gustavo A. Madero, Venustiano Carranza, and neighborhoods such as Tepito and Colonia Morelos.[7] Due to this, the line has a high rate of crime inside the stations and the trains, going from the presence of pickpockets and petty theft to armed robbery and sexual assault.[7]

In 2017, at least three violent robberies were reported, in which armed men entered the wagons and stripped the passengers out of their belongings.[7][8]
