what might be the reason that the entire state of BIHAR does not have a single shatabdi? a shatabdi that used to run(patna howrah) has been converted to jan shatabdi some ten years back.
a shatabdi special train should be run from PATNA to LUCKNOW via VARANASI and back leaving patna in the morning and coming back at night. if enjoys nice patronage (which i am sure it will owing to population dense region) can be regularised.
