The thing which worries while planning for Travel is that whether the train tickets will be available and the second thing will the waiting tickets be confirmed or not. Such a long journey without a confirm ticket ruins the enjoyment of the tour. Seeing all these problems Indian Railways has made an attempt to resolve this issue by Clone Trains.
Currently, Railway disables bookings after a waiting list of a train when it reaches 400 in Sleeper Class,300 in 3rd AC,30 in first class, and 100 in Second class, Now there will be no end of waiting and this will help Indian Railways to know about the no of waitings behalf of this they can make a decision to run clone trains or not.
As for now, this will be an experimental project by Indian Railways to provide guaranteed seats to every passenger who has booked a ticket, it will also Boost Indian railways revenues,
