BKSC just lacks one thing.. "Group Protest" which disables it from getting more trains. Take the example of PRR-HWH Rupashi Bangla Exp which was shortened till SRC earlier. After 3 days of shortening passengers of PRR directly banged the PRR railway management and forced them to re-extend it till HWH from its very next journey.
Like this if BKSC passengers do the same then might be the chances of good news.
