What is Hogged rail?

Hogged rail refers to a condition in railway tracks where the rail is not level but instead has a concave shape, typically occurring in the middle section of a rail line. This deformation can lead to uneven wear, increased maintenance costs, and safety hazards such as derailments. Hogged rail is often caused by factors like thermal expansion, heavy loads, and inadequate support. Regular monitoring and maintenance are necessary to address this issue and ensure safe train operations.
