Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 20185)

Data from "Udaipur Chitogarh Railway," Engineer (16 February 1934), p. 181.

Weight of the engine and tender together was 71.1 tons (159,264 lb/72,241 kg) loaded.

The Engineer reported that the engines were "fitted with specially large boiler and firebox, which ensures an amply supply of steam under all conditions." Their operating ambit were the UC's Ghat section, which had 1 in 50 (2%) grades.
