every 3 days, this train is running on a late chain, so the travellers who are going to travel by this from AII on 30 sep, 3 oct, 6oct etc and from sdah on 1 oct, 4 oct, 7 oct etc are likely to be severely affected .. since u r travelling from JP on 7th , so u need not worry as the other 2 pairs are running on time.
