It's not seems feasible, it's a click bit type news. As TTE has to check ticket in minimum 3-4 coaches how he will check for all persons in 10 minutes. 72 X 4 = 288 persons, if we assume only 50% of this capacity can TTE will check 144 persons ticket in 10 minutes. If TTE will take only 10 seconds to a person then he will take 24 minutes for 144 persons. How is this can happen?
