PERU’s government has approved a $US 3.89bn investment programme to modernise metro Line 1 in Lima, while extending the operating permit of concessionaire Tren Urbano de Lima until 2031 as part of a wider effort to increase capacity on the capital’s busiest urban rail corridor.

The investment package, announced by transport and communications minister, Aldo Prieto Barrera, will fund a comprehensive upgrade of the 34km elevated metro line, which serves 11 districts across Lima and Callao, and has carried more than 1.6 billion passengers since opening in 2011.

The programme includes the acquisition of 53 additional trains to expand the fleet to more than 90, implementation of CBTC, comprehensive refurbishment of all 26 stations, reinforcement of the elevated viaduct, expansion of depots and workshops at Villa El Salvador and Bayóvar, and construction of a new interchange station at 28 de Julio to connect with Line 2.

CBTC will enable reductions in headways from 2min 30s at peak times to 90 seconds, increasing capacity to 48,000 passengers per hour per direction. According to the MTC, Line 1 will ultimately be capable of carrying up to 1.2 million passengers per day, almost double current demand.
