Overview
- SUBE stopped applying the 50% discount for journeys that begin on a train and continue on the Buenos Aires subte, a change that took effect on August 1, 2026.
- Other Red SUBE integrations remain active when trips start in the subte or stay within City jurisdiction and the system still uses a 120‑minute window with 100% on the first trip, 50% on the second and 75% from the third.
- The national Tarifa Social Federal, a 55% discount for eligible beneficiaries administered by the Secretaría de Transporte and ANSES, continues to operate and can combine with Red SUBE savings when those savings apply.
- City officials including Pablo Bereciartua and Jorge Macri say the measure responds to the national government stopping funding for interjurisdictional integrations and that the City can no longer absorb the cost, while national sources say the City chose the change.
- The immediate effect is higher daily and monthly fares for many commuters from the Province who take trains into the City and then the subte, and the dispute over who must finance cross‑jurisdiction subsidies remains unresolved.
