Suburban train in Mexico

Case studies



In 2005, Construcciones y Auxiliar de Ferrocarriles S.A: (CAF), through the company Ferrocarriles Suburbanos S.A. de C.V., was awarded the 30-year concession of the System 1 Suburban Railway, making this one of the largest projects in the history of CAF.

The project covers the construction, operation and commercial management of the railway, in addition to the provision of a public rail service.

Ferrocarriles Suburbanos is the new means of transport connecting the State of Mexico and the Federal District. In view of the transport requirements characteristic of large cities throughout the world, the Suburbano is the best option for long-distance travel at affordable prices. This eco-friendly solution offers comfort, convenience and safety.

The Buenavista-Cuautitlan route linking the City of Mexico with the four surrounding municipalities, has the capacity to transport 300,000 passengers a day, with an estimated number of 100 million passengers a year, in an area with a high and growing population and important economic activity for the region.
