Chalukya on both directions create problems at YPR. From Mumbai, it blocks enroute line from UBL to YPR. While towards Mumbai, it blocks line and platforms for 2-3 hours.
Anyway, being a pass through CR train, it is better to forget it's utility to Bangalore. Let it go to PDY/ TEN in any other route. Let it not disturb YPR.
Similarly, LTT CBE originally meant as Kurla Bangalore train is blocking DMM SBC line daily. Let it go via KJM SA.
Better...
more... not to talk about Udyan.
Unless SWR runs a train from Bangalore to. Mumbai, all these problems are bound to continue. How long you will survive without any exclusive train, at the mercy of other zone trains?
