Bhopal - Vja to Vskp 3AC - 18
So i have doubts how the train get filled up
1. Do the travellers from BPL, NGP upto VJA need to share only 18 berths and then get into RLWL max 18
2. New Delhi to Bhopal is in high demand for example friday dep from NLDS and 200 berths get filled up and they will go to current availability from BPL as RLWL takes only 18
3. How many RAC (28 berths correct me if i am wrong)and Tatkal are allotted for the train and how many berths are left for remaining quotas
