HATIA-IPR Exp aur Magadh Exp ka RSA rahega jaisa abhi hai .. 22nd Dec se 12401 number change hoga as that series belong to NR-NCR-NWR... aur new number mil jayega jo SER ka series hai..
dono alag alag train abhi bhi hai HATIA-IPR Exp aur Magadh Exp.. bas rake share karti hai..
raat me jo rake Hatia Patna...
more... Exp bankar Hatia se aata hai wo hi Patna se IPR chala jata hai PNBE-IPR Exp bankar (ye dono gadi merge hokar ek gadi ban jayegi ab ) aur evening 4pm ke aaspas jo rake subah PNBE-IPR Exp bankar aaya tha wahi Magadh Exp 12401 bankar nikalta hai.. abhi SER ke pas gaye Magadh ko 4 month hoga 20th ke aaspas isiliye 22nd se SER apni series ka number de rahi hai.
