The upgradation of the heritage Steam locomotive from a Coal-fired system to an Oil-fired one is a unique and challenging project that was taken up by TREC-STEP. The major problem of Railways of non-availability of good quality coal and also the punishing inhuman manual handling system has been addressed by the introduction of this technology. This challenging task was taken up by TREC-STEP with the confidence and conviction provided by its diverse group of experts drawn from its own Entrepreneurs, Academia, BHEL and other organizations. This project marks the introduction of new technology to the NMR. Trial runs with the upgraded system in place were meticulously planned and coordinated with the various Railway departments. As many as 70 successful trials were carried out on the MTP-ONR section over a period of 140 days just to make things absolutely flawless.
