Nai aisa nai keh sakte kyunki currently G-BPQ route hi hai without touching NGP but this route is more probably made for goods train and passngr trains are allowed on this route in the daylight as becoz of naxalite area is there from where this route is passing but i dnt knw whether any passenger train is there in night also thru this route and regarding JBP-BTC-G route most probably once open SECR will use this route for frieghts and slowly slowly they will start running many southbound/NGP bound trains from this route as this will become the shortest route b/w North-South connection and thats y IR ordered SECR to open this route within ofcl end date or before so that ET/NGP can be decongested
