Line 1 is 34.4 km long with 26 stations. The standard-gauge line is electrified at 1.5kV dc overhead, and is operated by a fleet of five six-car trains supplied by AnsaldoBreda in the 1990s and 19 five-car Alstom Metropolis trains delivered in 2011. A €200m contract was awarded to Alstom in July 2016 for an additional 20 six-car Metropolis trains together with 19 extra cars to extend the five-car sets to six-car trains. Delivery is scheduled for completion by 2019.

FGC has worked for Lima Metro before, when it carried out customer service and conflict management consultancy and training for Lima Metro in 2012.
