Tras dos horas sin servicio, las líneas B y C del subte ya comenzaron a funcionar.
El proyecto también apunta a mejorar la confiabilidad del servicio y reducir tanto el consumo energético como las emisiones de gases de efecto invernadero.
Abren las licitaciones para la construcción de la Línea F de Subte.

Overview

  • The city opened technical bid envelopes on Friday, Oct. 2, 2026, and confirmed two competing groups are now under technical evaluation.
  • One consortium is led by CITIC Construction with Ranken Railway, Supercemento, Eleprint and Panedile while the other pairs local Grupo Roggio with Italian tunneling firm Ghella.
  • Planned as a 9.8‑kilometre underground line with 12 stations between Barracas and Palermo, Line F will link with all six subte lines and two commuter‑rail stations and is estimated to carry about 300,000 passengers a day.
  • The procurement follows a two‑step process with economic offers to be opened after technical review, an official adjudication set for December 2026 and construction targeted to begin in early 2027.
  • City authorities estimate the work will cost about US$1.35 billion and are pursuing parallel investments including a CAF loan for Line B modernization and the purchase of 214 subway cars to improve capacity and relieve crowded corridors such as Line C.
