This train is a very huge demanded train from Odisha.
I am giving tip for Sleeper classes.
After boarding from BBS , go to Upper berth (in case having Lower berth seat , exchange with someone just for some time) and go to sleep. Telling you do this or else your whole "happy morning" will turn into a "Bad morning".
From BBS to VZM...

, specially between KUR to CHE , this train runs as a Intercity train. SL classes are packed with daily travellers and waiting holders. Beggars will give you a headache and transgenders will suck up your money. (They are very shameless)
But once train reached VSKP , It all becomes COMPLETELY empty. Seriously i was shocked to see the complete empty and cleaned SL coach after i woke up. All thanks to Ratnachal express which takes away all the intercity day travellers.
After this the whole journey from VSKP to SBC is a awesome one with full of heavy crossings and views of Mighty Godavari and Krishna rivers.
After VSKP , the next cleaning is done at BZA station and after that from BZA to SBC , it runs as it is , but still the coach condition of these ECoR is quite good.
I would suggest the VSKP folks who wish to travel to Bangalore, Take this train.
Because it is the only Non-VSKP starting train to bangalore who have General quota for VSKP to SBC also. So BBS & VSKP both share same quotas.
Best chances of getting confirm seats if you book well 1 week ahead of time in SL. AC coaches are very badly demanded for this train.
For VSKP to SBC , you can easily opt SL class (unless its not some Festive season like Pongal or Diwali). Best thing is Food.
The pantry is quite good and warm-good quality food is provided.
