Overview
- Trenes Argentinos staff ordered a preventive evacuation after a fire started beneath an entrance escalator and produced heavy smoke in the station's subsurface hall.
- Firefighters, three SAME ambulances and police set up a security cordon and worked at the scene to control the blaze and treat passengers.
- SAME transported one person for smoke inhalation and treated them in an ambulance; no other serious injuries have been reported.
- Station access from the street was closed and one branch of Avenida Brasil was blocked, and authorities limited entry to allow emergency vehicles to operate.
- Constitución is a major transfer hub linking suburban trains, the subte and many bus routes, so officials warn service and commuter conditions could change as authorities finish assessing the damage.
