The Ministry of Transport and Communications (MTC) announced on March 16 that the tunnel boring machine “Delia” has reached the Óscar R. Benavides station (E-06) in Callao, marking a new milestone in the construction of Line 2 of the Lima and Callao Metro, Peru’s first fully underground metro system.
This achievement completes the excavation of an 800-meter tunnel segment between San Marcos (E-07) and Óscar R. Benavides stations. The machinery advanced at an average rate of 15 meters per day during this stretch, maintaining steady progress on the project.
Since beginning operations, “Delia” has constructed nearly 13 kilometers of tunnel and passed through thirteen stations: Circunvalación, Nicolás Ayllón, 28 de Julio, Cangallo, Manco Cápac, Estación Central, Plaza Bolognesi, Parque Murillo, Tingo María, La Alborada, Elio, San Marcos, and now Óscar R. Benavides. The next phase will see “Delia” continue toward Carmen de la Legua (E-05) and Insurgentes (E-04), where its journey will end.
Of the total planned 27 kilometers for Line 2’s tunnel network, more than 25 kilometers have already been built. Only the section between Óscar R. Benavides and Insurgentes stations remains to be completed.
Meanwhile, another tunnel boring machine named “Micaela” is working on constructing a branch for Line 4 of the Lima and Callao Metro. It is currently heading toward Quilca station (E4-06), with plans to proceed through Morales Duárez (E4-07) and Carmen de la Legua (E4-08).
According to MTC data as of January 2026, “Delia” had achieved an 86 percent completion rate for Line 2’s tunnel excavation while “Micaela” had reached a 53 percent completion rate for Line 4’s branch. Overall progress for Peru’s first underground metro stands at approximately 80.66 percent.
Once fully operational, Line 2 is expected to transport over 660 thousand passengers daily with fast and modern service. Projections suggest that by 2030 demand could exceed 1.2 million users each day.
