LIGHTS WARN DAY TRAINS

Simple System Which Eminent Signal Engineer Believes Will Be Found to Be Effective. With the recent developments in lenses for signal purposes, according to Thomas. S. Stevens, signal engineer for the Atchison, Topeka and Santa Fe railroad, it is now practicable for the different colors to be readily distinguished in daylight at a distance of 2,000 feet. All the complicated mechanism necessary for the mechanical operation of signal arms are eliminated and replaced by simple electrical circuits which are far more efficient and economical to maintain. In the majority of cases two 25-watt lamps are used behind an eight-inch lens. Indeed, It appears that the problem with this type of signaling is to provide a light signal sufficiently visible in bright sunlight which will not make the signal too prominent at night.
