New Terminal always is pain as it divert trains feasible for connectivity from main stations.
JBP incoming trains at PCOI needs underpass not to block UP/DN track for signal clearance. Further holding line need to exist between Karchana-Cheoki so JBP bound trains dont choke track for clearance!! JBP UP/DN Twin line parallel to trunk from PCOI with DDU bound track cross trunk via underpass later on could eliminate issue to great extent. Usually trains get delayed between Karchana-PCOI!!
