Overview
- Trenes Argentinos began the long-weekend interventions on Saturday, August 15, executing planned multi-day closures that suspend the Tigre ramal and prevent Mitre services from reaching Retiro through Monday.
- On the Línea Mitre the Tigre branch is fully interrupted for the three days while the José León Suárez and Bartolomé Mitre branches will operate only between Belgrano R and their Buenos Aires province termini.
- The Línea San Martín will have timed suspensions that close Retiro, Palermo, Villa Crespo and La Paternal during near nine-hour windows on Sunday and Monday to allow track and signaling works.
- The Roca line’s Alejandro Korn ramal will be limited to Temperley on Sunday, August 16, because crews will occupy both tracks to update catenary equipment and medium-voltage distribution.
- Trenes Argentinos says the works are part of an Emergencia Ferroviaria plan that has already renewed 34 km on the Tigre ramal and aims to renew about 40 km of track and replace 47 km of third rail, but it warns weather could pause operations and urges commuters to check official channels and use recommended bus routes or alternate trains.
