Mexibús Line I

The Mexibús Line I is a bus rapid transit (BRT) line in the Mexibús system. It operates between Felipe Ángeles International Airport in Zumpango, Ojo de Agua in Tecámac and Ciudad Azteca in Ecatepec de Morelos. It was the first line to be built and to be opened. It was inaugurated by the governor of the State of Mexico, Enrique Peña Nieto on 1 December 2010 with 24 stations. Another station was opened later. It is 20 km long and was used by approximately 130,000 users per day during 2012. The line has four different types of services, including a service exclusive for women and children. The line operates with 75 articulated Volvo 7300 BRT buses painted white with red, light green and dark green trim. It began free operations in October 2010.
