Mahamana 2S in Ranchi - Patna - Howrah Janshatabdi Express.
One of the Two Rakes of this Janshatabdi has 2 Mahamana Coaches i.e. D-5 & D-12.
Seats are more comfortable than the ordinary JS coaches with Beautiful Interiors. Has Charging Points too.
I personally felt that these type of coaches attract more passengers.
