Data from "Metre Gauge Goods Locomotives Rohilkund-Kumaon Railway", The Locomotive Magazine, Volume XXVI [26] (13 March 1920), p. 62.
As noted in Locobase 10180 for the O-class passenger engines, this goods locomotive design was a standard for most metre-gauge railways of the time. The program which continued for almost 50 years (1874 to 1922) saw over 1,000 engines built (see Locobase 3039).
Unlike the passenger engines, however, F goods locomotives had inside plate frames and inside valve motion serving outside cylinders. These had Belpaire fireboxes. Seven Rohilkund-Kumaon examples completed the 20-engine order; see Locobase 20815.

As noted in Locobase 10180 for the O-class passenger engines, this goods locomotive design was a standard for most metre-gauge railways of the time. The program which continued for almost 50 years (1874 to 1922) saw over 1,000 engines built (see Locobase 3039).
Unlike the passenger engines, however, the freighters had inside plate frames and inside valve motion. Some railways preferred round-top boilers, others prescribed Belpaire-firebox designs. The locomotive described in the specifications had a round-topped boiler.
