The quickest way of getting from one terminal to the other is by the inter-terminal transport: Aerotrén which operates from 5 in the morning to 11 at night, with departures every 15 minutes.

Passengers with connecting flights are given exclusivity but must show their ticket (electronic or normal), or their boarding pass to be able to take the Aerotrén.

People who wish to travel between the two terminals without a connecting flight can use the inter-terminal bus service which departs from the following locations: T1 - Gate 6 / T2 - Gate 4. The price per passenger is 5 Mexican pesos.

To operate two terminals at the same time, one opposite the other, at a distance of around 3 kms., was an important challenge. Both terminals attend national and international flights, and thus, there was a need to establish some kind of transportation between them for passengers with connecting flights.

After due consideration, the choice was made to install a driverless, automised train system; electricity was the form of power chosen and for the propulsion: the use of a 6-km.-cable system. The carraiges are transported along a tubular steel base.

The functional characteristics of the Aerotrén are similar to that of a cable car, but the train has some competitive advantages over the former: lower cost, higher capacity and greater flexibility, especially regarding the trajectory of the trip.

So as not to interfere with the everday running of the ongoing airport operations at the two terminals, two elevated stations were constructed for the reception and delivery of the passengers.

The train initiates its trip from an elevation of 10 metres opposite Terminal 1 (T-1). During the trip, passengers are transported around the perimiter of the airport, around the national car parking facilities until reaching an elevation of 13 metres.

Once arriving to the Boulevard Puerto Aéreo, the elevation is reduced so as to permit aircraft landing activities; once past this zone, the train again rises to an elevation of 10 metres and finally delivers passengers directly to the check-in area of Terminal 2 (T-2), at a height of 6.5 metres,

Each of the train's (4) carriages has a capacity for 25 passengers and the system is supported by concrete columns that rise from a depth of 26 metres.

The train can transport up to 6,800 passengers on a daily basis. The trip takes just under 7 minutes for the 3 km. journey at a maximum speed of 45 kph.
