Signal Mast (EPS)
Signals are most commonly mounted on trackside masts about 12 feet (3.7 m) to 15 feet (4.6 m) high to put them in the eyeline of the engineer. Signals can also be mounted on signal bridges or cantilever masts spanning multiple tracks. Signal bridges and masts typically provide at least 20 feet (6.1 m) of clearance over the top of the rail. North American railroad signals generally fall into the category of multi-headed electrically lit units displaying speed-based or weak route signalling. Signals may be of the searchlight, color light, position light, or color position light types, each displaying a variety of aspects which inform the locomotive engineer of track conditions so that he or she may keep their train under control and able to stop short of any obstruction or dangerous condition.
