For the fourth time coaches of a long-distance super-fast train got uncoupled in less than three months.
On Monday the Guard coach, which is the last coach of 2009 Shatabdi Express, uncoupled at Mumbai Central. Uncoupling happens when two coaches separate after the lock connecting the two gets unlocked.
"The train was traveling at around 10 kmph when the incident occurred. The coach was then coupled and the train left 30 minutes late. The reason will be investigated," said Western Railway Chief PRO, S. Gupta.
The accident could have been serious if the uncoupling had occurred when the train had touched its average speed of 100 kmph after leaving the station. "We have found that the maintenance personnel who couple the coach didn’t lock it properly," said a WR official.
The Research, Design and Standard Organisation are presently studying the reasons behind such events in other super fast outstation trains such as Rajdhani and Duranto Trains. The apparent reason sighted by officials is the nature of coupling connecting two coaches or an engine with a coach. Earlier trains were connected with a coupler at the center while buffers were on the sides.
However with the up gradation in technology both buffer and coupling have been combined. This means that all long distance trains are now connected using Central Buffer Coupling, which is a combination of buffer for absorbing jerks and coupler for joining two.
