What is the purpose of using the high rail for alignment measurements in a curve?

Using the high rail for alignment measurements in a curve serves the purpose of facilitating the marking of stations at regular intervals. This is essential in track alignment and maintenance, as it aids in ensuring that the curvature of the track is precise and maintains consistent alignment, which is critical for train safety and operational efficiency.

Marking stations at regular intervals allows for easier monitoring and inspections to be performed, ensuring that the curvature remains within the designed parameters and helps in scheduling maintenance or adjustments when necessary. This regular marking is also important for planning and operations, as it provides reference points that can be used for scheduling train movements and conducting maintenance efficiently.

While establishing a baseline for safety, determining optimum train speed, and complying with regulations are important, they do not directly relate to the practical application of marking stations using the high rail during alignment measurements. The primary aim in this context is to establish a systematic approach to maintain the integrity and safety of the rail infrastructure through regular monitoring and marking practices.
