About the Roca Train
The Roca Train is one of the most vital rail lines in the Buenos Aires metropolitan area, carrying over 1 million passengers daily under normal conditions. It links the city center with the southern part of the province, covering districts such as Avellaneda, Lomas de Zamora, Almirante Brown, Florencio Varela, and Berazategui.
The A. Korn branch is among the busiest, stretching approximately 50 kilometers from Constitución. In recent years, riders have frequently complained about service frequency and train conditions, though investments have been made in track renewal and signaling upgrades.
