Mitre Line’s Tigre Branch to Shut Jan. 10–Feb. 28, With Suárez and Mitre Services Turned at Belgrano R

Officials say the summer window allows a full power cut for signal testing, enabling work that cannot be done at night.

Overview

  • Trenes Argentinos announced a 50‑day suspension of the Tigre branch for safety and modernization works under the national Railway Emergency.
  • During the closure, José León Suárez and Bartolomé Mitre services will not reach Retiro and will operate only between their cab endpoints and Belgrano R.
  • The program includes renewing 7,700 meters of track in hard‑to‑access sectors, interventions on the Figueroa Alcorta and Dorrego bridges, third‑rail upgrades, and commissioning of a new signaling system.
  • Signal works at the Retiro approach involve installing 28 signals with ATS balises, 16 point machines, and 70 track‑circuit boxes, with dynamic testing requiring a total power cut.
  • Authorities cite rails and sleepers over 40 years old and more than 40 slow‑order segments; about 20 km of new track have already been installed toward a plan totaling 40 km of track and 47 km of third rail, with travel alternatives to be posted on official channels.
