SURVEY OF CAST STEEL TRUCK SIDE FRAME AND TRUCK BOLSTER REMOVALS BY MEMBER RAILROADS AND PRIVATE CAR OWNERS

A survey was made of cast steel track side frames and truck bolsters removed from service for reasons other than normal wear. Critical areas for side frames were compression and tension members close to journal boxes. Critical areas for track bolsters were in the center near the center bearing. The incidence of removal of these units increases with service life. Bolsters are removed 2.4 times more often than side frames. Changes in specifications should equalize this replacement rate.
