I understand what you are saying...
But there is no tracks anymore between Jharia and Dhanbad...
They had to be dismantled due to the Jharia underground fire! And there is no way connection can resume because the fire is still burning...
Under JRDA, the entire town of Jharia is still being shifted, after this shift is complete a new Jharia station and a new...
more... line was supposed to be built...
With now, the DHN-CRP line now decomissioned, this is the only way that train can run from DHN towards ADRA-BKSC without going via GOMOH...
ECR & DHN Div don't want to burden GOMOH any further, hence as per this article, after a meeting at Garden Reach, ER, ECR & SER all three have agreed to run 17005/17007, RNC-BGP Exp, RNC-KYQ Exp via this route...
RNC-JYG is set to short terminate and originate from DHN!
