A NON-DESTRUCTIVE METHOD OF MEASURING INTERNAL RAIL FORCE

Stability of continuously welded rail (cwr) can be monitored by determining the longitudinal force that exists at all times in the rail. British Rail Scientists have developed a rail-force transducer which permits rapid simple accurate measurements to be made of stress changes unaccompanied by changes of length. Using the results, the stress-free temperature of the rail is easily calculated. Transducers are cylindrical in shape and are installed by gluing in holes of the standard fishbolt size drilled in the rail's neutral axis. Readings from the transducers are taken at any time by using a portable measuring instrument.
