Tren Suburbano

Line 1 was projected to carry 100 million passengers annually.[8] From the period of June 1, 2008 through July 7, 2008, the service carried one million passengers, or an average of approximately 30,000 passengers per day, which is a rate far below the annual projections.[9] As of January 31, 2010 according to the head of Comercialización y Administración de Riesgos del Ferrocarril Suburbano stated that Line 1 of the Suburban Railway of the Mexico City Metropolitan Area served an average of 88,000 passengers per day.[10] As of the end of 2012, ridership reached 132,000 per day, short of the 192,000 per day the private operator needed to stay solvent due to the high initial upfront cost and debt schedule. In 2012, the system ran an operational profit, but the profit was not high enough to cover accumulated debt repayment yet.[11] Ridership had increased to 184,000 per day as of 2015.[12] As of 2018, the Tren Suburbano had an average of 200,000 passengers per day.[1] Due to the COVID-19 pandemic in Mexico, ridership decreased 73% as of May 2020.[13]

Trains are scheduled every 6 minutes during peak hours.

As of 2021,[14] the fares are 9.50 pesos (approximately US$0.45) for a trip of three or fewer stations and 21.50 pesos (approximately US$1) for longer trips of four or more stations. Fares are paid using a rechargeable card that costs 15.00 pesos.[15]

A proposed branch route toward the Felipe Ángeles International Airport (AIFA) in Zumpango is expected to be completed by the first third of 2024.[22] It will run 23 kilometers (14 mi) from Lechería station through six new stations to the airport terminal.[23] The line follows the route of a previously proposed branch from Lechería to Jaltocan, and it will pass through the municipalities of Tultitlán, Tultepec, Nextlalpan and Zumpango.[24]

In the 2000s, authorities proposed extending the system to a length of 242 kilometres (150 mi),[25] in order to reduce Mexico City's heavy road traffic congestion and air pollution. In most cases the system would follow existing rail lines, with potential grade separations similar to the ones done on the initial segment.

In December 2006, SCT announced that approval had been given for a route extending 19.3 kilometres (12.0 mi) from Jardines de Morelos to Martín Carrera; and another route running 12.8 km (8.0 mi) from Chalco to La Paz.[25][26][27][28] Neither line was ever built.
