The Bengal Nagpur Railway class P was a class of four 4-8-2+2-8-4 (“Double Mountain”) Garratt locomotives. It was developed from BNR class N and BNR class NM. The Anuppur-Chirmiri section had severe curves and it needed an engine with a trailing bogie. Its boiler was slightly enlarged similar to the NM.

It could haul 1,500 long tons (1,500 t) load up a 1 in 91 gradient.
