mumbai rajdhani is more important and prestigious then bhopal shatabdi coz it connects two biggest metro cities of india and bhopal is very small in front of delhi and bombay. the reason behind the less speed of mumbai raj compared to bhopal shatabdi is it heavy 18 coach load. bhopal shatabdi is only a 11coach train. but priority wise mumbai rajdhani is higher then bhopal shatabdi and it is always fully reserved
