A new step has been taken in the consolidation of the infrastructure of the infrastructure of the Lima and Callao Metro. The Delia tunnel boring machine recently perforated the diaphragm wall of the Tingo María station (E-10), after advancing 766 meters from its exit at Parque Murillo (E-11).
The machinery, specialized in subway excavationhas already completed more than 7 kilometers of galleries since it was assembled at the San Juan de Dios station (E-19). This performance is in line with the project’s objective: to provide Lima with a modern rail network that connects key areas of the capital and Callao more efficiently.
Arrival of the Delia tunnel boring machine in Tingo María
Line 2 is the first completely subway infrastructure in the country. The Ministry of Transport and Communications (MTC) and the Urban Transport Authority for Lima and Callao (ATU) are supervising the execution of the project, which aims to reduce traffic congestion and travel times.
Delia’s progress implies technical progress and a direct benefit for thousands of citizens. Stations connected so far include San Juan de Dios, Circunvalación, Nicolás Ayllón, 28 de Julio, Cangallo, Manco Cápac, Estación Central, Bolognesi, Parque Murillo and now Tingo María.
Expectations and upcoming achievements
Drilling towards future stations will continue at a rate of approximately 14 meters per day, according to the project’s technical sources. This efficiency is key to maintaining the planned schedule and delivering a functional line on schedule.
It is expected that, with Delia’s arrival in Tingo Maria, the structural work will be accelerated and the next sections will be prepared. According to the Peruvian news portal La República, the entire project includes 27 stations and will benefit more than one million people daily.
Infrastructure for better urban connectivity
The subway rail system has a crucial relevance in improving urban mobility. The operation of tunnel boring machines such as Delia, along with others such as Micaela, allows work to be carried out without interrupting urban life above ground. This reduces environmental impact and facilitates cleaner project execution.
In addition, the technical conditions of Lima’s soil require highly engineered solutions. The TBM is equipped to work in complex geological conditions and its progress is monitored in real time by subway infrastructure experts.
This type of progress reinforces confidence in the country’s ability to execute works of great technical complexity, setting a precedent for future urban mobility initiatives.
