Common Systems Used In Rail Track Inspection

By Essie Osborn


One of the most common things that cause railway accidents is catastrophic rail failures. Due to the increase in the number of accidents caused by railway flaws, people are coming up with new technologies and systems that can examine these flaws at the early stages to allow for repairs. The rail track inspection systems come in a variety of options.

Among the most common systems is the head checker that comes with certain mechanism that works to inspect rail edges for faults. The high-resolution digital line scan camera in the head checker enables it to check very small faults on the rails. These cameras work to capture and store information in certain database to ease the repair work.

Joint check systems are used to examine railway joints and fish plates for flaws. These systems work at high speeds to check rails for missing bolts, nuts or crack formation in the fishplates. Many joint check systems are controlled using a wheel encoder that is fixed with digital line scan cameras and wheel encoders that check and record data in a track state protocol.

Other popular structures are the digital crack checker recording systems. These devices have the ability to examine and evaluate the condition of the concrete sleepers and ballastless tracks. Many of them work under high speeds and can perfectly detect any crack structures in rails. The system also has a database where it stores the obtained data.

Another system available is the railway checker that uses automated mechanisms to inspect railway surfaces such as the concrete sleepers for potential and existing errors. They are mounted with scan cameras and distance sensors that are very effective in examining railways sleepers and ballasts for errors. Their designing allows them to work at high speed when examining rails.

Wire checkers are as well common systems used to determine the thickness of railway contact wires. Wire checkers come with infrared laser light illumination components and a couple of high-speed linear cameras that are used to scan wires to determine whether there are any faults. The design of these systems enables them to be used when taking both small and large measurements.

Vegetation checkers are also common systems that are used for railway inspection purposes. The main purpose of these structures is to examine railway bed structures, track edges and areas and generate the appropriate information concerning the inspected areas. The vegetation checkers are created to operate at high speeds to ensure quick, safe and accurate results.

Another system available is the profile checker, which is created in such a way that people can use it to inspect the cross, and vertical sections of railways. Its design enables it to be utilized to measure the corrugation amplitude, gauge and profiles of the rails. Manufacturers fix this system with information checkers and data recorders to help enhance their performance. In some models of these systems, you would find high-tech mechanisms such as the distance sensors and scan cameras that improve their functionality.
