Those who are making their end to end journey (from SBC to MYS) in CC coach. Better to book in Shatabdi in CC class.
Rajya Rani CC fare: ₹ 260 (normal), ₹ 240 (in Current availability)
Shatabdi CC fare : ₹ 305 (With lunch), ₹ 225 (Without lunch).
So basically, Shatabdi without food is always cheaper, and 1 hour faster. (Depart SBC 30 minutes...
more... after Rajya Rani, arrive MYS 30 minutes before Rajya Rani)
