Overview
- Trenes Argentinos confirmed a full suspension of the Once–Moreno ramal for four consecutive days from July 9 through July 12 to allow concentrated infrastructure work.
- Planned tasks include renewal of track apparatus in Caballito, signaling upgrades in Liniers, work on underpasses and platforms, cabling over the Reconquista river and fourth-track interventions in Moreno.
- Two recent physical attacks on train staff in late June forced a union stoppage that halted night service and highlighted growing safety tensions for railway workers.
- Diesel branches Moreno–Mercedes and Merlo–Las Heras will keep running during the shutdown, but long‑standing cuts and fragmentation of bus routes leave western Greater Buenos Aires with limited and costly alternatives.
- The line has logged roughly 30 days of disruptions so far in 2026, users report inconsistent official updates during incidents, and commuters should expect crowded buses, longer waits and higher travel costs during the July closure.
