Sir, though Liluah Dankuni is the shorter route for trains using the Howrah- Burdwan Chord, but there is another line, which would be used by ER trains ddeparting from Shalimar, and SER trains departing from Sealdah. The ACC Link Line connects Santragachi Jn. and Andul (of SER) with Dankuni Jn. and Rajchandrapur (of ER). SER trains from Sealdah (to be introduced Sealdah- Puri Duronto) would take the line from Rajchandrapur to Andul Jn., and ER trains from Shalimar (to be introduced Shalimar- Patna Duronto) would take the line from Santragachi Jn. to Dankuni Jn..
