Shyad spring me nai indian railway k track quality me hi problem hai jo high speed me iss spring k saath wear and tear kar raha hai....
Ye train 150 k speed me aise hilta hai jaise derail hi ho jaayega.... Maintaince to iss rake ka vase bhi bekar hai, running bahut zyada hai,aur speed to full hi hai.....
Mere hisab se to track me oscillation k vaja se spring me problem ho raha hai.... Combined with poor maintenance offcourse...!
