Purpose A railway vehicle traveling on a stable rail line has a fixed amplitude and frequency, and hence it has constant sound values. However, line defects on the rail line alter this constant sound. Related to this, each defect type varies the reference sound value in a different way. In this study, audio signals originating from the three most common structural defects in …

Rail wear in the railway transport system on the straight, inclined, declined or curved path, as well ... Although wear can be significantly reduced by using high quality steels and lubricants,

Whereas maintenance of the track is now predominantly executed at fixed intervals or based on yearly inspections, the accurate prediction of rail wear could considerably improve the maintenance...

This paper's aim is to assess the rail wear evolution of railway tracks under mixed traffic conditions for sharp curves. Field investigations were conducted over a period of five years, at 800 points on a rail track, for two curves that underwent maintenance interventions: sleeper and rail replacements during measurements. Lateral and vertical wear measurements were …

Based on the lifetime data analysis of the sharp-radius R300 tunnel section curves (Fig. 7), the wear out behaviour is more significant (( beta > 2 )) for the high rail gauge corner wear, while slight wear out behaviour is observed for the low rail head wear (( 1 < beta < 2 )).For the moderately sharp curves of radius R500, the wear for both viaduct and tunnel foundation …

Tee Rail and Crane Rail are available in both new and relay quality. A note about Relay Rail: Relay Rail is rail that has been previously used and then removed due to abandonment of lines or replacement for heavier rail. NARP inspects the relay rail, removes defective rail, reconditions, and then grades it for wear.

Rail quality has heretofore meant tight dimensional toler­ ances, high static strength, and good resistance to wear. Track and mechanical deparunents strive to reduce their respective wear replacement costs for rail and wheels; a generation of this competition has led to increases of 35 to 50 Brinell points in wheel tread and rail head ...

Rail damage-related accidents have taught us some hard lessons as we build our railways. When a high-speed train in the UK snapped a rail outside the curve on its journey from London's King's Cross to Leeds in October 2000, four people were murdered and more than 70 were injured. A faulty rail caused an Indian express train to derail in ...

The railroad standard watch was known as the "Standard Watch" to railroaders and railroad organizations (literally, a watch that met the railroad time service standards) and as the "Railroad Watch" to the watch trade and now to collectors.There are many different aspects of these watches which create a large range subjects upon which a collection can be focused.
