There is a drawback here. The train mentiond 17611/17612 Was Changed To 22101/22102. It is extended from Manmad which is CR and to NED which is SCR including maintenance to SCR from CR. As maintenance is changed from CR to SCR so Number must be changed. Means you can keep Old MMR-CSTM TT as usual and just add the extension TT here.so you can keep the current TT from MMR-CSTM and add the extended version TT Only. So both cases are different we cant compare as same case.
But here the Destinations and Origination stations not changed including Halts and maintenance also not changed. please observe it.
