I think it's high time now that ER should think of increasing the quota of Durgapur and Asansol in Sealdah Rajdhani exp. Almost huge numbers of seats are getting booked from Sealdah and passengers are changing their Boarding point to Asansol and Durgapur to get a confirm berth in the train as both these stations have very low allocation of seats. The same thing is very much visible from the current availability status of this train between SDAH and these stations
