Data from "Metre Gauge Mixed Traffic Engine with Wootten Firebox, Bombay, Baroda & Central India Ry., Metre Gauge Section", Locomotive Magazine, Volume XXVI [26], (15 May 1920), pp. 94-95.
Baseed on the "Major Shelley", an express passenger locomotive built in the railway's Ajmer shops in 1913 (Locobase 20114), this lcomotive sought to wring as much power as it could from the "very inferior quality Jherriia coal." So locomotive superintendent W S Fraser recast the design to include a Wootten-type firebox with a considerably larger grate. He kept the cylinder volume, but fitted smaller drivers

This is the British Engineering Standards Association passenger version of the HSG shown in Locobase 4251. It is a freight engine with Belpaire boiler of good size compared to the cylinder volume.This Vulcan product has cylinders 1" greater in diameter than the HP 4-6-0 shown in Locobase 4241, which represents a later decision to reduce cylinder volume. See that entry for a full description of the BESA intention and varying views of its utility.
Data from "4-6-0 Express Locomotives, Bombay, Baroda & Central India Ry., Metre Gauge Section", Locomotive Magazine, Volume 19, No. 254 (15 October 1913), pp. 230-231.
Modified from a saturated-boiler design in BB&CI's Ajmer shops under the direction of locomotive superintendent W S Fraser, this engine was the first metre gauge locomotive in India to be fitted with a superheater. It used a slightly modified version of the Belpaire firebox developed for the Standard Committee's metre gauge passenger engine.
Claims that early returns indicated a 20% drop in coal use and a "considerable" drop in water consumption are right in line with other observations of the time.
