History
Line 6 was opened on 21 December 1983, in the section that goes from El Rosario, serving the estate Unidad Habitacional El Rosario -the biggest estate in the country, to Instituto del Petróleo. The latter became the first transfer station when it was connected to the already existing station of Line 5.
Three years later, on 8 July 1986, the second stretch of the line was inaugurated: from Instituto del Petróleo to Martín Carrera, connecting with Line 4.
According to the Mexico City Metro Plan published in 2018 by the Sistema de Transporte Colectivo, Line 6 would be expanded from Martín Carrera eastbound towards Villa de Aragón station of Line B. This extension would have a length of 5.69 km (3.54 mi) and five new stations.
This brief starts where responsible research should: with the source description of “Mexico City Metro Line 6” as metro line in Mexico City. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as metro line in Mexico City. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Jun 19, 2026. The linked authority identifier is Q3238990. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1983, 2021, 1986 and 2018.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
