i have seen this train on 27th december, it was running with 17 coaches, this augmentation is to clear the huge waiting list of christmas season, my question is that why IR dont make this train permanent 17 coacher?? its a highly demanded train in this route and runs jam packed whole year, if it can be made 17 coacher permanently then the pressure of mandovi will be relieved to some extent.then why IR runs this with only 10 coaches??
