Overview
- Service remains limited, with trains running between Belgrano C and Tigre and from Belgrano R to José León Suárez and Bartolomé Mitre.
- Officials estimate roughly 15 more days of operational checks but have not set a firm reopening date for Retiro.
- The postponement follows missed targets of March 1 and March 8 as the operator validates the renewed signaling using empty-train runs and staff training.
- The works include 29 km of renewed track, 120 km of new signaling cables, upgraded signals, level crossings and bridges, with travel-time reductions projected later in 2026.
- Passengers report longer journeys and higher combined fares during the restriction, heightening frustration over the rolling delays.
