Overview
- Service will bypass Liniers on Oct. 31 from 10:00 to 15:00, followed by a full‑day closure of the stop on Nov. 1 and Nov. 2.
- The upgrade targets the stretch between the Barragán and Granaderos level crossings to improve safety and curb control‑system failures.
- The operator warned that unfavorable weather could postpone or suspend the works.
- On Nov. 2, San Martín trains will operate only between Retiro and José C. Paz, and the Retiro–Junín long‑distance service will be suspended.
- Further works set for Nov. 15–16 at Caballito will require a third‑rail power cut, restricting Once–Moreno trains to the Liniers–Moreno section.
