Zyada trains nahi ja rahi ASN. Jo planned hai wo bhi Daily nahi except Patliputra Express. Baaki sab weely/bi-weekly hai. And, you have to share the load of GMO anyhow, there is no other alternative available. One option is available but SER and ECR are not considering it, via CRP-MHQ-BJE-JOC-ASN , this will avoid PRR reversal and retain BKSC. Since, BKSC-IPTN-TLE line is still awaiting CRS inspection, it is not available.
