if u wish to run ur dream train via MGS-BSB-SLN-LKO-BE-MB-NDLS then only this can run on ur given expected time....
Via CNB running a duranto at peak time at which maximum trains are on route is not al all possible......
at night time the shedules of trains are fully packed and there is no space for duranto coz a duranto needs a wide signal clearence and that would be the cause of problem.....
