Bhopal Shatabdi: chalti hai ek dum hawa ke mafik, speed aisi ke ruka de traffic - Varun

At stations like Ernakulum Junction, how long before the train is due to depart do you recommend arriving at the station?
I gather that information on which care one (you) is/are booked in now only shows obn station displays, not within the train's cars. Is this correct?
