A Rajdhani isn't a normal passenger (tdl cnb) which will be controlled to pass any train & the zone won't be asked for it even if it is passenger or goods or any train a proper log book is maintained for every train and submitted to board.So had there been mistake on part of ncr, action would have been taken right after the overtake with big headlines in morning news paper. Moreover twitter handle of gm/drm is not to answer why this overtake, why that overtake.Does it even makes normal passengers bother about it ? Ranchi Rajdhani has been overtaken many times by Sealdah Duronto and not one intertogated
on it, do you expect people of rajdhani in mid-night to be...
more... awake and enjoying speed thrash & suddenly after overtake of Shivganga they went into depression for their money ? A late departure from source means technical issue which may or may not allow Rajdhani to hit 130 MPS.
And DRM handle is not used by DRM everytime and I don't think the purpose of twitter handles is to answer fanatics about why this overtake took place.
