Railway mechanical engineer . both rails supported oncast iron pedestals with a pre-cast slab between the railand back wall; this design keeps the rail off the concrete walland leaves the beams and pedestals exposed where they canbe replaced in a few minutes if a failure should occur. Fig. 3 shows a dry pit used by the Bangor & Aroostook,and is similar in construction to Fig. 1, the difference beingthat the bottom of the pit slopes from the back wall to thecenter of the pit; the beam carrying the track is made of two70-lb. rails placed upside down to support the track; thepedestals are spaced 6 ft. Y% in. between centers and are builtof two 70-lb. rails back to back on end and encased in con-crete, the concrete being protected by a 3^-in. steel plate;these vertical rails are supported by two 70-lb. rails runninglengthwise in the foundation. The Buffalo, Rochester & Pittsburgh has built a pit ofType B at Lincoln Park, N. Y., shown in Fig. 4, whichseems to be a favorite design for a dry pit in cold Fig. 3—A Dry Pit Built by the Bangor & Aroostook This pit can be built with one track and a loading track, orif the length of the pit is fixed, several tracks can be builtside by side. This style of pit is constructed of a series ofcast steel buckets placed in shallow pits to receive ashes directfrom locomotives. There is enough depth provided underthe buckets to allow for drainage. The buckets are handledby means of an overhead crane from the pit directly to theash cars. The pits are of an unusual shape with slopingsides in the upper part and a narrow rectangular lower por-tion, old rails being imbedded in the sloping surfaces withtheir bases projecting l/% in. from the surface of the concrete;each parapet wall is capped with a 12-in. channel to whichthe track rail is bolted. The buckets have a capacity of 2cu. yd. each, each seated on the projecting rails of the pitwalls. When the buckets are filled the traveling crane carriesthem to the cinder cars where t
