To keep everyone informed about train movements, reliable and complete communications coverage is necessary. Denver & Rio Grande Western has achieved such communications coverage via its recently completed dispatcher-controlled, base-radio station program. Radio coverage provides two-way communications between dispatchers and personnel on rolling stock on main and branch lines, totaling some 1300 miles. Also, personnel in radio-equipped vehicles on adjacent highways can talk to or be called by dispatchers. By use of special tones, men in the field can alert the dispatcher to the fact that they wish to talk to him. A special muting device enables the dispatcher to have "peace and quiet" for planning moves, yet a light and bell will call his attention to a call from the field. This muting feature enables D&RGW to conserve radio frequencies in that only one frequency can serve for both end-to-end and train-to-wayside service. Dispatchers at Denver, Grand Junction and Salt Lake City can cover the entire system.
