Nothing is going to happen. So many years we keep seeing this in IRI and other forums. There are already reports where it is mentioned that there are too many divisions in any case. So many requests keep coming from all MP's for their respective states/constituency. I don't think railways looks at this with that much seriousness. Only thing that can be done is to merge Konkan railways with IR and while that is being done do some rationalisation. If one region demand is met, similarly other regions will also start asking. There are similar demands in Andhra, Jharkhand, Odisha and other places as well !!
