If 935 kms of railway lines deserve 2 divisions in the same zone (referring to Kerala), how many divisions would be required for a state having 2935 kms line (referring to Karnataka)? At present, karnataka has just 3 divisions but 5 zones are controlling. Even Uttar Pradesh may not be having this much complexity of zone and divisions.
It is necessary to create 2 more divisions and bring entire Karnataka into 2 zones from current 5 zones mess. Considering the practical geographical constraints, I am not suggesting being entire state railway lines to one zone.
