The '''Bengal Nagpur Railway class NM''' was a class of ten [[4-8-0+0-8-4]] [[Garratt locomotive]]s. This was modified [[BNR class N|N class]] [[Garratt]]. It had [[Thermic siphon]] and arch tubes for better performance. It worked on the [[Bilaspur, Chhattisgarh|Bilaspur]]-[[Katni]] line and [[Anuppur]]-[[Chirmiri]] branch line for hauling coal. Probably because of Poppet valves, they retired early.<ref name=5brinkster>{{cite web|title=5brinkster |url=http://sundar.brinkster.net/Garratt.htm |url-status=dead |archiveurl=https://web.archive.org/web/20131023060832/http://sundar.brinkster.net/Garratt.htm |archivedate=2013-10-23 }}</ref> <br />
