When it was running as Dhanbad Alleppey along with Tata Alleppey, there were only 8 sleeper coaches from Dhanbad. Ab jabse alag hua hain, sleeper coach has not changed at all. Abhi bhi 7/8 coaches hi hain. Isliye no change in quota. However I think quota might have increased in AC 3 tier, though not completely sure about it.
