This new route has also robbed it's WAP7 link till CSMT, I wonder why no zone has not yet provided Eloco to 16339/40 despite End to end electrification of entire route.
Can run via KJM in slot of 16331, also at SA bottlenecking due to arrival of 11022,17235 and 22652 in KRR - SA line, causes platform unavailability at that time.
