Abstract
Improvements in signaling systems for railway crossings or levels characterized in that said systems comprise railroad circuit means to monitor a section of railway track at a point close to the level crossing and detect the presence of any train in said section ; passage detection means to detect the passage of any train that could approach the level crossing, when passing through a device located beyond said section of railway track; and signal means sensitive to detecting the presence of a train in said section and detecting the passage of any train that will pass through said device, to give a warning signal to any vehicle located on the road when the level crossing approaches.
