Agreed. Agar karni bhi hai to short distance wali DBRG RAJ (via BJU) aur (via Rangapara) ko hi is route pe divert kardo but otherwise no RAJ required. SF bhi iss waqt loopline ki priority hai jinhe SF ki jagah HS thama di gayi. Jis area me huge amount of passengers sleeper me travel karna prefer karte hai us jagah pe VIP train dene ka logic samajh ke pare hai
