Sir even I belong to ALipurduar Division & as you know NJP is the crew changing pt of Katihar & Alipurduar Division..I'm not saying ur updates are wrong but no admin/member can say that on a particular day TVC GHY will arrive on PF#1A...it can arrive on PF#1(if arrives before 2041) & even in PF#2...Similarly Dn Train arrives @ PF#3 in most of the occassions,but during eveining time I've seen 12505 arriving on PF#1A(which is exclusively an Up PF)...also trains which originate from NJP almost always start from PF#1-2
