CAR ROLLABILITY ON GRADES

This report discusses the various factors which decrease the rollability of railroad cars. These factors include: center and side bearings of trucks; broken, scored or unlubricated bearings; tolerance of axle bearing and truck bolster in side frame; plus dragging brakes. Findings suggest methods to increase rollability of rolling stock with related savings, such as improve center and side bearings with good lubrication; use of rust resistant materials; redesign brake rigging to minimize dragging of brakes resulting in locking of the truck; and creation of a device to free brakes with air is bled from the system.
