Arnab da , Instead sending it via soooooo circular route,I would suggest you the following route for this train:
DBRG-DMV-GHY-NJP-RPH-BWN-(via CCLW-BTNG-BALT-ACC chord link)-ADL-KGP-BBS-VSKP-BZA-GNT-GTL-UBL-VSG.
With a diesel loco from DBRG to BWN. A electric loco from BWN-GNT. A diesel loco from GNT to VSG.
By this route, only a single loco reversal i.e VSKP would be required.
