I think KR means Konkan Railway means(K-KARWAR n R-RATNAGIRI), but now a days KR stand for KERALA REGION, because almost all trains stop only kerala region instead of KARNATAKA, GOA, MAHARASHTRA region.
Some trains like 22149/22150, 12484/12483, 16311/13612,12217/12218,12287/12288 there is halt in between udupi and Madgaon and also Madgaon and Panvel. Ratnagiri is very famous town Maharashtra Konkan region and also konkan railway division and same thing in Karwar also. Why rail board and Konkan Railway people not taken single risk to stop train not only almost all places in KARNATAKA, GOA, MAHARASHTRA that very helpful all the konkan people
