The new Mountain type locomotives are being run in apool with the older locomotives and consequently both arehandling the same trains on the same division. Both designshave the same size cylinders. Despite the smaller boiler,the new engines steam just as freely as the older ones, arerunning with :>ij in. larger exhaust nozzles, are makingbetter fuel records and take the same train 30 miles furtherfor water. The locomotives are provided with floating bushings inthe middle connections and the same attachments furnished.
