Thank you for the input. Timings adjusted.
Reason Thane was chosen is, I wanted to connect SGNR with Mumbai interior. Initially chose LTT, but since its already loaded up, chose Thane.
I know its busy, but this is a suggestion that it could be better. Also it would connect towns in PGT - MDU line with Mumbai. So far no trains are connecting Mumbai interior with SGNR or the towns I mentioned.
