PERU: A consortium of Barcelona metro operator TMB and consultancy Ayesa is to supervise the upgrade of Lima metro Line 1, under a US$6·8m three-year contract awarded by government body Ositran.

TMB and Ayesa are to audit the investment plan that includes additional rolling stock, power supply and signalling upgrades, and the remodelling of five stations.

Last year Alstom won a €200m contract for the supply of 139 metro cars for Line 1. These include 20 six-car trainsets and 19 cars to lengthen from five to six cars the existing trainsets in service on Line 1.

The fleet expansion is being undertaken in response to growing ridership, which reached 320 000 passengers a day in 2016. This was originally the ridership forecast for 2035. The extra rolling stock and other upgrades will allow peak headways to be shortened from 6 min to 3 min, enabling a capacity increase from 20 000 passengers/h to 48 000.
