SR and SWR are getting free run of a CR train, by using Chalukya rakes. SWR is happy as it has distrubed their own zone people,by slowing down this train.
Why SR or SWR is not running any train (don't say weekly via Salem)? People are breaking their backs in the Krishnagiri-TV Malai road, which is the worst road I have ever seen in my life.
But, coming to the point, why SR can't give some water and clean up the train at VM or PDY for this UBL train?
