What is one method for de-stressing rail as per BNSF CWR policy?

The method of de-stressing rail as per BNSF Continuous Welded Rail (CWR) policy involves a specific procedure outlined in E.I. Chapter 6 (6.2.6) De-stressing CWR. This chapter provides detailed guidelines on how to manage the stresses that can build up in continuously welded rail due to temperature fluctuations and other factors. De-stressing is crucial because it helps prevent the formation of buckles and other distortions that can compromise the safety and functionality of the rail.

Using established practices from this policy ensures that the rail maintains its structural integrity and performs reliably under varying conditions. It involves controlled cooling methods or adjustments to the rail—techniques that are specifically designed to reduce the internal stresses without causing any damage to the rail itself. This focus on a standardized method ensures that all rail workers can apply these practices consistently, enhancing safety and operational efficiency across the rail network.
