The derailment of a lightly loaded 12-ton insulated box car and subsequent collision with the Up "Royal Scot" passenger express passing at 20 mph was ascribed to poor spring adjustment. Whereas 2-1/16-in. was the prescribed distance from the top of the eyebolt to the underside of the solebar, the eight eyebolts on this van ranged from 1/16 to 2-7/16 in. In view of the number of similar derailments involving four wheeled car with 10 ft wheelbases approaching the velocity limit of 60 mph, it was recommended that (1) there be greater availability of spring adjustment facilities, (2) lock nuts be welded after eyebolt adjustment, and (3) unauthorized adjustment of lock-nuts be prohibited.
