For a conventional jointed rail track rated at 45 MPH, what is the required remedial action if crosslevel measurements indicate defects?

In a conventional jointed rail track rated at 45 MPH, crosslevel measurements are critical for maintaining the stability and safety of the track. When crosslevel defects are identified, it indicates that the track is not level or has significant deviations which could potentially compromise the structural integrity of the rail system, lead to derailments, or cause excessive wear on the rolling stock.

When defects are detected, the appropriate course of action is to place the track out of service until the necessary repairs can be made. This ensures the safety of both the infrastructure and the trains that run on it. Operating trains on a track with crosslevel defects poses serious risks, and taking the track out of service is a necessary precaution to prevent accidents and maintain the overall safety standards of railway operations.
