The accuracy of verse TM stress free temperature measurements on straight track (RR-STR-96-001)

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. VERSE TM (VErtical Rail Stiffness Equipment) is a possible non-destructive method...
