Railroad tracks are used to support and guide locomotives in railroad transportation. The tracks can crack and cause trains to derail or flip, which could result in serious injury to lives and property.
Railroad track inspection from railroadtracusa.com/our-services/ involves using non-destructive tests (NDT) to identify railroad tracks in a planned manner to deal with any flaws that could lead to disaster.

Rails are becoming more compressed and impacted by the rapid development of heavy-haul and high-speed rails. The likelihood of rail damage is on the rise. It is important to inspect the railroad tracks regularly.
Non-destructive Testing (NDT).
Non-destructive testing refers to the measurement of the surface and inner parameters of an object. It does not destroy its physical and chemical properties of geometric integrity.
Ultrasound testing
Principle
Utilizing the propagation and attenuation properties of sound waves in the medium, as well as the reflection, refraction characters on the interface.
Application
Forged, rolled, and other workpieces or materials that have finer grains. This is used to detect internal flaws. It can also detect surface defects.
Magnetic particle testing
Principle
Flaw detection can be done by using magnetic force, or the interaction of the magnet and magnetic field. A defect is when a portion of the magnetic fields lines is exposed, which forms a leakage magnet field. The magnetic powder attracts the leakage field to form a magnetic track, which indicates the existence of the defect.
Application
Non-ferromagnetic defects can be detected in ferromagnetic materials like iron, nickel, and cobalt, as well as certain alloys.
