This design is in a degree experimental, but itseems to be well carried out and is promising of still furtherdevelopment. The first consideration was to secure a stiff frame which. a view of improvement In this important ele-ment in car design. There is an evident desireto get down to a four-wheel truck and to thiswithout sacrifice of safety, the 5 by 9 in. axle isemployed. There has been no attempt, so faras we know, by any railroad in this country tomake any change in the general plan of springand equalizer suspension, the usual construc-tion in this respect being followed. Saving inweight and first cost of trucks is desired andthis is accomplished by a reduction in the num-ber of parts, such as frame stiffeners, wheels,axles, boxes and bearings.
