This train already has coaches s-1 to s-11, A-1, B-1, B-2. I saw train today at chennai central station. I saw reservation charts for all coaches also. now from 09/05 it will have s-12 and B-3 also. At start 8 months back it had only 7 sleepers . now see what a hit train is this, I think next budget frequency will increase. adm plz update s11.
