Alstom's share of the contract is worth €130m and covers the supply of 70 additional Metropolis vehicles, which will enable Panama Metro to lengthen its trains from three to five cars and increase the fleet from 19 to 26 trains. The additional cars will be assembled at Alstom's Santa Perpetua plant in Spain and deliveries will start in early-2017.

Traffic on the 13.7km north-south line from Los Andes to Albrook has grown rapidly since its inauguration in April 2014 and weekday ridership has now reached around 215,000 passengers. Ridership on Line 1 is expected to increase further with the opening of Line 2, which will operate from the outset with five-car trains.
