Yes that is precisely the issue with KR. All other zones in India somewhere or the other are having upgrade in infra, station redevelopment & so on, but nothing in KR due to lack of funds. I remember seeing some proposals of the annual time table committee couple of years ago where some train proposed by SR or CR was rejected by KR stating that they desperately need to preserve some paths for goods train so that they get some revenues. Merging of KR with IR will be good from long term stand point but are there any technical difficulties in doing this ?
