After Cansaulim Majorda gets commissioned 37 kms (Cansaulim to Kalem) out of total 58 kms will be a double line on Vasco Kulem route.
Also Kalem to Kulem I think some forest clearances are pending that's why works not started except Kulem outers if it starts can be commissioned within 6 months as terrain is not too difficult and no houses near the tracks the entire track passes through forest.
