Falaknuma never compromised with speed. Shows 10 to 25 minutes normally sometimes 30 to 35 minutes early at every station I experienced it many times in Hwh- Bbs - VSKP - BZA section.
depends on controllers to allow that blazing run.
If
#train20 rake comes to SCR after 4 or 6 year's my best option will be Falaknuma's clone train non will regret.
