MAO doesnt probably have space to accommodate Sampark Kranti for a longer duration hence simply sending it to ERS as a weekly service. MAO to ERS already lots of trains are there. With its revised TT ( especially return timings from ERS to MAO), this weekly service is hardly of any use. Overall patronisation of it is quite low. Instead they can use this rake to conduct service from MAO to MYS ( Via MAJN). It can be a good option to explore.
