NEW COMPRESSORS GIVE N&W YARD PLENTY OF AIR FOR RETARDERS

At its new Roanoke, Va. automatic retarder classification yard, Norfolk & Western has assured itself of plenty of compressed air at 125 psi for retarder operation, even in emergencies. Should power fail, air from four 120 cu ft receiver tanks will supply air to retarders to control any cars being humped at the time of power failure. Also, the receiver tanks plus four new compressors with a combined capacity of 4,000 cfm will assure an adequate air supply for dual humping operations. Significant savings were obtained by use of heat exchangers in an improved recirculating compressor cooling water system, eliminating the use of city water.
