Trolleybuses in Mexico City
Transit system in Mexico City
From Wikipedia, the free encyclopedia
The Mexico City trolleybus system (Spanish: Red de Trolebuses de la Ciudad de México) is a trolleybus network serving Mexico City. It is operated by Servicio de Transportes Eléctricos (STE), which also operates the Xochimilco Light Rail and Cablebús systems. Along with other public transportation services, including the Mexico City Metro, Metrobús, and Mexibús, it forms part of the Mexico City Integrated Mobility System.

The system opened on 9 March 1951.[1][2] As of 2026[update], it comprises 14 routes, some of which operate on dedicated corridors with characteristics similar to bus rapid transit (BRT) systems. Until 2019, the routes were identified by letters, after which numbered route designations were adopted.[3][4]
Beginning in 2019, the system underwent a major modernization and expansion program under the administration of Claudia Sheinbaum. The program included the purchase of new battery-equipped trolleybuses manufactured by Yutong in China to replace vehicles dating from the 1980s and 1990s. The new vehicles can operate both from the system's 600 V DC parallel overhead lines and independently using onboard batteries, allowing them to travel up to 100 kilometres (62 mi) away from wired infrastructure.

Lines 1 to 7 are cross-city routes, of which 3, 4, and 7 are tangential routes, not reaching the city centre and generally oriented perpendicular to radial routes ("crosstown" route in American English). Line 9 is a short tangential route that is not "cross-city". Line 8 is a "feeder" route, feeding the city's metro system at Politécnico station and also line 1.
On October 29, 2022, line 10 was inaugurated from Metro Constitución de 1917 to Acahualtepec. The section from Acahualtepec to Metro Santa Marta was inaugurated in May 2025.[13]
