Hi, I gonna travel to MAS by this train from KJM next Friday. My ticket is in B2 coach. Heard that the CC of this train gets reversed every week. How can I find it out as B2 comes either at the first or last.. if it is last and I'm stand at the first, I should run like anything. Suggest me the best way to get into B2 as soon as the train arrives at KJM..
