The foresight of KR builders didn't extend to coaching terminals. Udupi is a big city, they could have built a couple of pitlines there or at Karwar. No PM infra on Karnataka part of KR.
Also proper PFs and other things like shelter, FOB, lighting are lacking at almost all the stations barring a couple of big ones.
The worst part is the PFs, all of them look like a heap of clay. full of slush when it rains.
