Is time pe , koi bhi train nahi rukti , so platform ki jarurat nahi padegi , passing trains loop se nikal jayenge. Overtake/crossing karna ho to fir us particular time pe aaju-baju wale stn me karwa sakte he. Jab trains 40-50 ghante tak continuesly chal sakte he , to sirf 14 ghanto ke round trip ke liye , itna TAT kafi hona chahiye
