Customers can call 9-1-1 in all areas of the subway system where 5G connectivity is available, using any cellular carrier. If an emergency occurs on a subway train, please press the Yellow Emergency Strip located above the windows. This immediately notifies the Operator and Transit Control of the emergency, ensures the subway will stop at the next station and emergency personnel are dispatched.
