All suggestions are extremely resourceful. A brief summary :-
MAQ/MJN should be separated from PGT(SR). Either a new division is carved straightaway or keep MAJN/MAQ under MYS (SWR) until a new division is carved out .
Simultaneously, KRCL can be absorbed into IR by splitting between SWR and CR . Mangaluru -Karwar- Madgaon should be given to the Newly carved Mangaluru division...
more... of SWR along with MAQ/MAJN-SKLR-HAS .
Some new lines that are expected to see light in near future like Kadur – Chikkamagaluru – Belur shall also come under the mangaluru division.
I hope IR seriously gives it a consideration.
