Your need for stopping a train at Kharagpur could be met by many other trains.
IR has introduced various trains:that caters to various sections of the society, and also different locations, starting from Rajdhani to Passenger trains. Not only that IR is also aware of Religious and Tourist element and hence trains like Mahaparinirvan train for Buddhist followers, and Maharaj , palace on wheels for foreign tourists are run. Apart from this IR runs many special trains during Festivals and religous ceremonies. And IR has also arrange regular trains for Pilgrims which connects from East to West and North to South etc.

more... Duronto is introduced with purpose to cater to those who are travelling from Point to Point.
Those who want to get down on the intermmediate stations have to board SF, Mail/Epress or Shatabdi/Rajdhani trains that have stoppages at desired stations.
Creating the demand for stoppages is an attempt to 'Thwart the Purpose of Duronto'.
This does no good to Morale of Adminstration of IR.
