The mining industry boomed in the dawn of the 1700s. Intending to enhance it, rail transportation was utilized. A year after that, the public was afforded the chance of travel not by horses, but by those noisy, chugging, and smoke emitting locomotives. Passenger safety then became a top priority of concern, and the checking of this was mandated and was known as rail track inspection.
Both and steel and metal comprised the tracks. Concretes are also used as a foundation. It is a must that the base of the train should be very strong and sturdy for it to be able to withstand the mammoth of a load that it has to carry and the long span of mileage that it has to cover.
The first and earliest known methodology implemented was done only visually. Thus, fatalities arising from the locomotive defects caused by transverse fissure are blamed on human failure on ocular misses. This cause of defect happens when there is a perpendicularly lying crack to the length of the trail. Detecting this defect caused by wear and tear was solely dependent on the eyes of the inspector, albeit the distance that has to be covered run for miles and miles.
Safety issues weighed down heavily, and many companies and institutions came up with approaches for inspection. Banking on the realization that if it will not be pushed through, fatal accidents may claim the lives and assets of many. Strategies involving high technology are used nowadays to better address the improvement of the trains when it comes to speed.
It is given that modernization has also taken its toll on railroad transportation, making it faster by means of electricity whereas before it ran on coal fired engines. Electricity made train travel speedier, thus increasing the fatality of accidents, if it will arise. In physics, the higher the speed, the stronger the impact of collision between two moving objects.
Long gone are the primitive tools of the engineers of the 80s. Jackhammers are now replaced with the complex computers that can detect flux leakage. Magnetic induction took center stage after ocular inspection. Now, several people are employed in putting into action one challenging tactic.
Testing procedures in medicine was tapped. Xray, or formally known as radiography, is used to look in to the composition of a specific object. Through Xray, spots in the tracks that are repaired using welding may be studied, whether in three or two dimension, making inspection easier.
As an Xray uses images, ultrasound detects flaws in welding and points out the exact spot that needs to be checked through sound waves. Ultrasound is the most popular methodology. It is also an active member of the medical procedure package for clinical patients.
In the near future, technicians and engineers alike hope to use a method that requires less number of staff and less exposure to accidents. As of now, the methods mentioned somehow requires contact with a speeding train. Lasers are projected to be the answer to this. Rail track inspection is something that should not be taken lightly.
