BKSC-KGP Passenger (by KGP) service via ADRA and BKSC-TATA MEMU(by CKP) is in hold by the respective divisions. ADRA will receive rakes soon and you will find them going via BKSC-CRP-BJE route.
RNC's trains have only one fruitful route to join grand chord which is via BKSC. I agree BKSC is literally excluded from ADRA div. MEMU services since long because of SER's lag in taking approvals.
Just let the TT line get 90 kmph CRS approval and you will see MEMUs via CHAS. Already work is going on to fix...
more... some unusual curves. By February next year, there will be MEMU services.
ADRA-RUKNI will be doubled so we will get a whole ADRA-BKSC double line. Talgoria-BJE section doubling is not a big deal.
