CAF is leader of a consortium including Thales, Isolux- Corsán and AZVI, which was awarded a €690m contract in December 2014 to equip the 57.7km line, which will include 4.7km of tunnels.
The fleet of 30 trains is being assembled at CAF’s Beasain plant in northern Spain. Each 160km/h five-car set will accommodate around 700 passengers.
The six-station line is forecast to carry around 230,000 passengers a day and will offer a 39-minute journey time between Zinacantepec and an interchange with the Mexico City metro at Observatorio.
The Pesos 46.97bn ($US 2.14bn) project is due to be completed in April 2018.
