I agree. I grew up traveling between Bombay and Calcutta in its glory days. It is still an excellent train, runs on time and gets good priority. But, that is where the Gitanjali heritage begins and ends today. Now, it is overload of stoppages, and that ugly RSA. If IR can't afford four dedicated rakes for this train, may be it should consider getting it three LHB rakes, and make it a Duronto with a few stops. It should be possible to cover the distance in about 25.30-26 hours:
CSTM: 06.00
Bhusaval: 12.00-12.10...

Akola: 13.45-13.50
Nagpur: 17.00-17.10
Durg: 20.20-20.25
Raipur: 21.00-21.05
Bilaspur: 22.25-22.35
Rourkela: 02.05-02.10
Tatanagar: 04.05-04.15
Howrah: 07.45.
Return: 19.45, reaching Mumbai around 21.30. (12-hour layover with SER, 8+ hours in Mumbai).
