hlw iri members...i'm in dilemma....actually i have to go tatanagar from katni on 24/01/16 and hv to reach latest by 1800 hrs. on 25/01/16. I have decided the link katni to bsp and bsp to tata. i hv figured out these train #15159 #18508 #12854 from katni and #12869 from bsp...now the question is which train to prefer from katni so tht I can catch #12869. what about fog nd which are the worst hit trains among those 3 from katni.... Thank you......
