Line 3 will extend 38 kilometers entirely underground, incorporating 29 stations with capacity to transport up to 2 million passengers daily. Line 4 will span 13 districts with 28 stations and is projected to serve approximately 600,000 passengers per day, strengthening connectivity across the metropolitan area and complementing the existing network. ProInversión also highlighted additional rail projects under the APP mechanism aligned with the National Railway Development Plan, including the 280-kilometer Lima-Ica Railway and the 245-kilometer Lima-Barranca Railway, both designed to integrate with the metro system.
Separately, ProInversión confirmed that the Line 1 expansion obtained technical and economic viability after completing pre-investment studies. The amendment will be signed in June 2026, enabling investment to begin in the second half of the year. The intervention requires an estimated investment of 14.1 billion soles, equivalent to approximately US$2.7 billion, and includes the CBTC train control system to reduce headways from three minutes to 1.5 minutes during peak periods. The expansion will add 31 new trains to the existing fleet of 39 trains, all of which will be modernized. Manuel Wu, chairman of the concessionaire’s board, stated that current capacity of 600,000 daily passengers will increase to one million, with infrastructure prepared for future demand of 1.2 million.
The Line 1 expansion will be financed entirely by the private concessionaire and includes construction of the 28 de Julio interchange station to connect with the future Line 2. Del Carpio indicated that engineering work will commence in the first year, with civil works beginning in the following year and major interventions completed within two to three years. ProInversión confirmed no immediate tariff adjustments are planned, with any future changes subject to Ministry of Transport and Communications authority. Peru’s current railway network totals 1,957 kilometers, of which 1,704.9 kilometers are for public use and 252.1 kilometers for private use.
In a parallel development, ProInversión disclosed an infrastructure investment program exceeding US$38.9 billion to strengthen Peru-Brazil connectivity through bioceanic corridors and multimodal routes. The program includes 97 projects distributed across three geographic axes. The Northern Amazon Axis comprises 35 projects totaling over US$8.7 billion across eight northern regions, including airport improvements in Jaén, Yurimaguas, and Rioja, along with port terminal and river transport projects. The Central Axis groups 33 projects and five contract amendments worth more than US$17.3 billion in six regions, including the Port Terminal of Pucallpa, the Chimbote International Terminal, the Chinecas Project, and various airport modernizations. The Southern Axis includes 29 projects and three amendments totaling over US$12.9 billion, featuring the Juliaca Dry Port, the Majes Siguas II project, the Port Terminal of Ilo, natural gas distribution initiatives, and port terminal developments in Tacna and Corio.
ProInversión also announced advancement of energy sector projects exceeding US$400 million in southern Peru, covering Arequipa, Puno, Cusco, Tacna, and Ayacucho. The Las Joyas Photovoltaic Plant in Arequipa represents an estimated investment of US$252 million. In Puno, three electricity transmission projects totaling US$135 million are under development, linked to the San Román-Yocara-Maravilla connection in Juliaca, the Nueva San Gabán-Puerto Maldonado link, and the Tintaya Nueva-Nueva San Gabán connection with associated substations. Tacna’s Los Héroes-Garita 220 kV link is valued at US$36 million, while Ayacucho’s Muyurina-Mollepata connection totals US$10 million. Between 2002 and 2025, ProInversión awarded 75 electricity sector projects under APP and asset project modalities for a total of US$10.8 billion, tripling national transmission line extension from 9,700 kilometers to more than 30,000 kilometers. In the southern region specifically, ProInversión has awarded 28 projects worth over US$4.7 billion. The agency projects adjudication of 18 electricity projects totaling US$903 million nationally in 2026, including major transmission initiatives grouped under Groups 1 and 2 of the Transmission Plan.
