Yesterday Indore and Patna express train got derailed resulting in many deaths and injuries to many passengers who were traveling in the train. It is indeed a great tragedy . Rail fracture is said to be the cause of the accident .
I have heard about bone fracture . But the term rail fracture is new to me. I was curious to know what it is .
The steel rails found in railway track are strong and durable . They can safely carry many hundreds of thousands of tonnes of traffic in their life time .
Small defects may be present in rails at the time of manufacture or while installing them and went unnoticed . These small defects may grow as more trains pass over and finally result in the breakage of rails .
Most broken rails occurs in winter season . In very cold conditions rails may be five degrees below the air temperature . This puts the rails under lots of tension and they become more vulnerable to breakage at the point of defects as trains pass over them .
What we can do to prevent rail breakage ?
1 . By regularly removing the small defects from the rails by grinding the surface .
2. If a track is heavily used , then more frequent examination has to be done .
3. The bolted joints between the rails have to be replaced with welded joints .
4 . The rails in the problem area must be replaced with new rails which can withstand higher worn out.
