Dear brother, SGNR ppl don't require the extension of Brahmputra mail. Rather what was genuinely required was a dedicated train to NDLS via SDLP-RE. The extension of TKJ-SDLP was an effort exclusively on the parts of MP of SGNR. What we actually need now is a dedicated train to Mumbai, Chandigarh, and Beas and no extension. Hopefully we will get these in next few years or so.
