This train is shown to take least time from Hwh to Kanpur. How can the source station of this train be so close to howrah as the hint indicates and even if so how can it reach faster than rajdhani being a passenger train? Just type trains from HWH to CNB, you will find this one on top, to your surprise. Moderators please correct this , it may be some other malikpur, also update the average moving speed of this train
