Aerotrén

The Mexico City International Airport Automated People Mover System Project was started on August 12, 2005 when a contract was signed between the airport owners Aeropuertos y Servicios Auxiliares (ASA) and DCC Doppelmayr Cable Car. The system was completed by November 2007 at a price of €52 million.[1]

The system was built and designed in a joint venture with Ingenieros Civiles y Asociados (ICA), Mexico's largest construction company.

The area around Mexico City suffers from soil settlement, and this had to be allowed for. The elevated guideway structure has the ability to be adjusted for ground settlements. Steel adapters between the steel truss and the concrete columns allow later height adjustments to compensate for any ground movement.

A single-track, single train, Cable Liner Shuttle design was chosen. The installed system is 3,025 metres (9,925 ft) in length and operates at a speed of 45 kilometres per hour (28 mph) between the two terminal stations. Vehicles connected to a cable, driven from under one of the stations, that propels, accelerates, and decelerates the train.

The train is composed of four cars, each holding 26 passengers and making of a total of 104 passengers per train. An option was included for lengthening the original four car train to six cars, providing an increase from 540 pphpd up to 800 pphpd.

Only connecting passengers can use the system, who must have a valid flight boarding pass to board. Travel time is 5:45 minutes and the train pauses (dwells) for 60 seconds on each station. When the system closes for maintenance, passengers are ferried between both terminals in buses.
