For many years, we have seen a train product introduced by former govt losing its value after a new govt comes into power. For instance, earlier LHB was limited to Rajdhani and Shatabdi category trains. Now the extra money you pay for Rajdhani/Shatabdi category trains is only for its "official" time table.
Duronto livery that was based on specific concepts of the then RM, is gone. Mahamana which charges more has been seen being used for some other train, as told by some member.
Hence, It is just a matter of time.
