Didn't you see 15035-slip Uttarakhand Sampark kranti Express schedule before posting all this??? which departs MB at 19:10 and reaches RMR at 20:40....
Even if other trains take 2 odd hrs from RMR to MB then also how much time difference remains, is it not a matter of fact.
The calculation I shown which according to you was "totally wrong" involved the time between RMR and MB to be 1.5 hrs which in no case is impractical, even for the sake of argument I agree to increase it to 2 hrs then...
more... also the total time becomes 7.5 hrs being far less than almost 12 hours as depicted in current TT.
It is endless if you believe in fallacies, misapprehensions, trying to deceive people by wrong deceptions. else, a dullard or a moron can only be supposed to come up with selective arguments.
