In order to make sure that rail track is free of flaws inspection is done on a regular basis. Rail track inspection is a very common practice done very frequently to identify any problems that may lead to failures of catastrophic nature. This practice has been taking place since many centuries because track defects are one of the leading causes of accidents.
United States was one of the first countries to encourage such type of inspections. Now, almost all around the world, this practice is regularly maintained in order to identify any defects. It is an unfortunate thing that still many accidents take place because of unfair management decisions and poor analysis done due to human error.
If the inspection is done properly, one can identify all sorts of external and internal flaws and errors. United States is one of the biggest countries and almost more than a million dollar is simply allotted for the purpose of inspecting rails for damages and flaws. Similarly, many other countries, allot different budgets for the same purpose. It is only possible to correct a damage only if it is identified on a prior basis.
In the event that surrenders and defects are not rectified in a convenient way, they may prompt unnecessary mischances and in most dire outcome imaginable, derailment could happen also. Awhile ago, when engineering was not helpful, these kind of inspections were outwardly done. Auditors used to take after the train tracks and paid special mind to any harms or defects.
Visual inspecting method was not very impressive as it still led to the fact that more accidents used to happen. These accidents might even get worse and lead to train derailments as well as loss to the human life. It was not before the year 1927 when Dr Elmer Sperry came up with a rail inspection car that used magnetic induction to identify any sort of damages.
With the advancement in technology, new methods have been implemented and they prove to be very useful. Even a minor damage or flaw can be easily identified which enables the authorities to keep the railway track in a good condition and many accidents are avoided. Entire rail needs to be inspected every time and usually such sort of inspection takes place once a week or sometimes once a month.
It is a fact that train traffic has increased over the recent years and it has become more heavier and more crowded which means regular maintenance is requires as well. Also, in order to enhance the journey times, train speeds have increased tremendously as well. This is the reason why a more quick and efficient inspecting is required. Laser technology is also used in this process in order to keep a track on railway geometry.
It can be observed that more advanced technology is on the way which will improve the abilities to inspect in a more thorough and precise manner. Newer models of rail inspecting cars are operating out there and all of them are fully equipped with the latest technology gadget.
