No doubt BKN/BME extension is illogical, not coz many stops at NWR but with 1+1 extra Rake & 67-80 hours TAT @ BKN/BME!! Run days need to be scheduled to minimize TAT for better utilization of Rak!!.
Rescheduled run days with 1 extra rake each, both BKN Duronto & BME SF can easily run as weekly or Bi-weekly Duronto & SF till NDLS/ANVT along with extension!!
