its a big problem for th epassengers in the train. lunch during the journey from asn to kgp is ok. caterer will serve food but the order will be taken from dgr. during the night journey u have to take food with u. as there is no confirmity during the journey from bbs to bza.so mind it. the last day journey is nothing to worry about. stopaege in gudur jnc and mas will give a lot of time to buy food. also caterer will be available from gudur jnc. but load urself from gudur/mas to ypr for the rest day as the stoppeges in jtj is only 5 mnts. so be careful about the matter. :)
