Ask katihar and purnea people what ignorance is. As per your comment it can also be said that if NFR wanted it could have diverted trains towards South via katihar seeing the demand pattern of katihar junction in one and only yesvantpur express and we can also use such emojis like "ЁЯШнЁЯШн" but we understand trains will only go through the mainline for South which is kne kdpr mldt line. Similarly for rajdhani trains towards Delhi the main line will always be NJP BOE(towards salmari) - KIR. I do believe MLDT should get a dedicated connection for North which will benefit biggies like mldt bgp jmp etc Similarly KIR direly needs connection for South which is totally dependent on HWH SDAH
