Italferr's 66-month contract is worth around $US 6m and includes the management of project interfaces during the construction phase.

The Consorzio Metro Linea 2 consortium of ACS Dragados and FCC, Spain, Salini Impreglio, Italy, AnsaldoBreda, Ansaldo STS and Cosapi, Peru was awarded a 35-year PPP concession to finance, build, operate, and maintain the line last year by Peru's private investment agency Proinversión. The consortium is providing $US 1.2bn in financing for the $US 5.8bn project.

The 27km east-west underground line will connect the district of Ate Vitarte with the city centre and Callao on the Pacific coast. The line is expected to carry 644,000 passengers per day with a journey time of 45 minutes between Ate Vitarte and Callao.

The PPP contract includes construction of an 8km branch to Jorge Chavez International Airport, which will eventually form part of Line 4, as well as 35 stations, a depot, electrification, signalling and telecoms systems, and the supply of rolling stock, which is expected to cost around $US 871m.
