The accuracy of VERSE stress free temperature measurements on curved track of 1,500 m radius (RR-STR-96-045)

A comprehensive auditable record of rail stress free temperatures (SFT) is an essential part of the safety management system to avoid track buckling in hot weather. Existing SFT measurement techniques are destructive, and hence are expensive, disruptive and slow. VERSETM (VErtical Rail Stiffness Equipment) is a possible non-destructive method of...
