this train is named kolkata rajdhani... howrah technically is not a part of kolkata...becoz there was no dedicated station at kolkata then and sealdah rly stn was not in a position to handle rajdhanis then it was started from howrah... now that there is a dedicated rly stn kolkata i think it shud be shifted there.... commuting problems are huge for hwh stn... huge traffic jam is really disgusting... this will help the passengers only sir.... another rajdhani as u suggested can be started from hwh.... lhb rakes is neccessary... if not possible provide icf rakes for the time being
