This is not the solution.
This always happen. Duronto were introduced with fare a little less than rajdhani but same services. but then duronto's fare were increased and made equal to rajdhani fare. Both Rajdhani and Duronto concept were hit.
However, Suvidha or Premium concept was a Failure! Equalizing Rajdhani Fare to Suvidha is surely mad thing.
Making Shatabdi fare equal to Gatimaan fare,...
more... atleast that could have been acceptable.
What use to happen actually was like this for example take 12951, CK Quota few seats booked, Premium CK no seats booked, and GNWL is low. It is obvious those CK and PRM CK seats would be allotted to GNWL passengers, that's what most people used to do including myself.
I have even travelled in NDLS-BCT Premium Express but paid just Rajdhani fare+41 rs extra thats it.
IR has realized this.
