Nothing? And you suggest increasing the travel time which is actually going back in time, when with each passing year the travelling time should come down which is progress
Why didn't the authorities of that section plan tripling/quadrupling, electrification as and where necessary, improving the signalling system and all such measures required for smooth operations? When they very well knew that being trunk route the load will always remain high and it will only increase with passing time
It is complete mismanagement on the part of authorities there...
