SOME PROBLEMS OF RAILWAY OPERATION AT HIGH AXLELOADS

J L Koffman, Dms Fairweather

Open publisher page 1 citations

Abstract

Long high-axle-load trains create cracking, shelling, crushing and corrugation of the rail head while weight transfer further accentuates the situation. Worn tire profiles can reduce contact pressure by 30 percent, but excess cant will increase crushing on the inner rail and axle-loading must be considered in relation to rail steel quality in the track. Three-axle locomotive power trucks set up higher lateral forces than two-axle types. Locomotive and car suspension characteristics must be considered in three planes.
