V-shaped rails, known as guard rails, are essential safety features on railway tracks. Positioned between the running rails, they help prevent derailments, especially at critical points like switches and crossings.
By guiding wheels back on track in case of an off-track event, these guard rails significantly enhance the stability and safety of the trains. They act as a secondary support system, ensuring that even if a wheel deviates, it is swiftly corrected.
This design not only protects the train and its passengers but also maintains the overall integrity of the railway infrastructure.
