⚠️ Roca Line Service Reduced: What You Need to Know
Updated August 13, 2026 – Based on official reports from Transporte AMBA (the public transport authority for the Buenos Aires metropolitan area) on August 12, 2026 at 2:59 PM.
The Roca Line, one of the busiest commuter rail lines in Argentina, is currently operating with reduced service on the Bosques via Temperley branch between Plaza Constitución and Claypole. This disruption follows an accident in the town of Florencio Varela, located in the southern suburbs of Buenos Aires.
Service status: 🟠 REDUCED – Trains are running less frequently than usual, leading to longer wait times and potential delays.
Which Branch Is Affected?
The Bosques via Temperley branch is a key route connecting the southern Greater Buenos Aires area with the capital. It passes through major stations such as Temperley, Adrogué, Longchamps, and Claypole before reaching its terminus at Plaza Constitución – the main hub for the Roca Line in downtown Buenos Aires.
The affected section spans from Plaza Constitución to Claypole, directly impacting thousands of daily commuters who rely on this line to travel to and from the city.
What Does “Reduced Service” Mean?
When Transporte AMBA declares a service as “reduced”, it means that trains are running at a lower frequency than the standard schedule. This does not mean the service is suspended, but passengers should expect longer intervals between trains and potentially more crowded conditions. Travel times may increase significantly, especially during peak hours.
