Overview
- Trenes Argentinos restored service to Retiro on March 12 for the Tigre, José León Suárez and Bartolomé Mitre branches after concluding operational trials.
- Empty-train runs validated the new access-to-Retiro signaling, with the operator reporting satisfactory results that confirm safe operating conditions.
- Works replaced 120 km of cabling and installed new signals while migrating from a century-old system, a changeover that required disconnecting legacy equipment and suspending access since January 10.
- Parallel upgrades renewed 7.7 km of track on the Tigre branch, bringing the modernized stretch between Empalme Maldonado and Tigre to 29 km along with 13 station areas, 16 level crossings and 12 bridges improved.
- Nighttime track works on the Tigre branch will continue to limit daytime impact, and Trenes Argentinos projects about 10 minutes less travel time by mid-2026 with a further roughly 7 minutes by year-end; the Suárez branch timetable now starts later and ends earlier with several early and late trains withdrawn.
