How could I go about obtaining test samples of rail sections with negligible and significant levels of internal stress?

You could work with a railroad or a rail manufacturer or plan a visit to the Transportation Technology Center in Pueblo, CO, where rails are available for testing. We don’t have a catalog of rails with specific amounts of residual stress, but we do have a couple of locations on track with known Rail Neutral Temperatures (RNT).
In this topic, please remember that we aim to measure longitudinal rail stress or RNT due to the rail being constrained on the track and changes in rail temperature. We are not interested in measuring residual stresses within the rail, although they can affect RNT measurements.
