Yes KSK should be re routed via ypr-Gtl-rc-sc-ngp-bpl-nzm...It is a fully electrified line n has a better mps than through the existing route......It can reach nzm at the same time without any delay n can save 10 min in sc .......n also many people who prefer ksk from ypr have a problem if they r getting down at kcg....Sc can be a better option
