How BNSF Manages Mud, Rock, Water and Snow Detection
Most railroads operate through at least some mountainous territory along their lines, but perhaps no road faces a greater challenge than BNSF.
Operating through some of the most mountainous territory in the western U.S., the railroad must constantly be on guard for mud and rock slides, floods, and snow blockages and slides.
BNSF recently published a piece in its “Rail Talk” series that Railway Track & Structures thought would be of interest to readers. It’s reproduced below, with permission:
When mud, rock, water and snow are on the move, sometimes they find their way onto railroad tracks. That has to be resolved promptly so trains can operate safely. Trackside detectors alert BNSF to obstructions that have shifted onto our tracks. These sentinels either set the signals to a restricting state or warn dispatchers, who alert train crews of the potential hazard.
