Bhai ZBTT mai train ko iss tarah revise kiya hai ki unko faltu overtake ke liye kahi khada nhi karna pade.... Overtake ke liye trains ko additional time diya jata hai taki wo overtake ke kaaran or jada late na ho
Or ZBTT ussi tarah ke time ko hataya hai.. or bhi kai faltu technical stopage time diye jate hai train ko usko kam kiya hai...
But Slack time is very necessary for trains....
ZBTT...
more... ka matalab ye thodi ki slack time nhi hoga
