I agree with you... I am addressing the point "The only capital connected by railways but does not have any premier trains like Rajdhani, Shatabdi, Duronto, Sampark Kranti, Rajya Rani, Jan Shatabdi......" Excepting Garibrath.
Especially I was addressing the word "ONLY". Nothing else but purely for informational purpose. Gandhinagar is still the only state capital connected to IR but not having premier trains terminating, Since PDY is a UT though has a legislative govt.
