Kalka Shatabdi used EOG cars which were modified to be used as power cars to supply the power from the loco's HOG to the rake ( HOG locos will still require one power car to distribute the power to the rake ). I don't know if it is running on HOG now, but even if the rake has an EOG car, it is possible that the train is running on HOG, and the EOG cars are just being used as power cars ( with the diesel generator switched off).
