The '''Bengal Nagpur Railway class P''' was a class of four [[4-8-2+2-8-4]] (“Double Mountain”) [[Garratt locomotive]]s. It was developed from [[BNR class N]] and [[BNR class NM]]. The [[Anuppur]]-[[Chirmiri]] section had a severe curvature and it needed an engine with a trailing bogie. Its boiler was slightly enlarged similar to the NM. Due to its water and coal capacity being less than that of N, it could run on 75&nbsp;lb/yard rails. It could haul {{convert|1500|LT}} load up a 1 in 91 gradient.<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 />
