IMHO, this train should be halted at RNG, UDL, and an extremely underestimated station like DDJ...as this train is non-SF, so no difficulty is supposed to arise in giving its stoppage, especially at DDJ. If stopped at DDJ, people living in that area will be able to go to BWN or ASN without boarding SDAH-SMI or rushing to KOAA/SDAH. Same reason applies for utility of halt of KOAA-JSME Pass at DDJ...DDJ badly requires some north bengal-bound trains also to stop here officially, for eg--Tebhaga exp, Teesta Torsa Exp, Maa Tara Exp, Hate Bazare exp, thus increasing connectivity between DDJ and north bengal...these north bengal-bound trains can be easily halted at BP too....
