I am posting this tip for 12074 based on my journey experiences from BLS to HWH. I traveled in the 2S class.
1. Cleanliness: The train compartment was clean enough. I expected it to be dirty but I was surprised. Kudos to the passengers for keeping the train clean as I did not spot any cleaning crew.
2. Food: On board catering is quite active. They sell all sorts of items like cake, biscuits, chips, cold drinks, lassi, water, tea, coffee etc. Prices are taken according to MRP. They were...

selling items even after KGP.
3. Punctuality: Super punctual. It started with a delay of 30 mins from BBS but reached KGP with a delay of 15 mins. It would have reached Howrah with only a delay of 5 mins but was stranded at Tikiapara and Howrah outer for quite sometime owing to what amounts to about 20 mins delay. Train has a superb run.
4. Tickets: Tickets are easily available in 2S. Even at the last moment, about 100 seats were still left. For AC however, getting tickets is quite difficult as the y sell out quickly.
Also for a general tip, if you are boarding from one of the intermediate stations, getting overhead luggage space can be quite difficult. The same is the case for other CC trains too. Also, if you are a single traveler and have booked a window seat then you probably might not get it(especially if they are occupied by female and aged people). For aged people, I do not mind but really get irritating when healthy people do not move. Also, there is no trouble of daily passengers on this train. Overall I would give this train a 6/10 based on my experience.
