I would first wait for April rush for the need of these trains but I agree that Humsafar Express from Howrah should've started from Patna or Ranchi, Not NJP as it has KYQ BNC Humsafar, while others don't have a single Humsafar
Antyodaya was very much needed because of the Unreserved rush in Howrah bound trains from Kerala, I have seen the rush myself and the train was very much needed
