Class Details by Steve Llanso of Sweat House Media
Class S-636/C30 (Locobase 2409)
Data from 2 Jan 1961 publicity handout from the NSW reproduced at [
] . This source notes that some of the C30s on the North Shore line had 19" cylinders and 175-psi settings for more tractive power. See also "'Double-Ender' Tank Locomotive, New South Wales Government Railways", The Locomotive Magazine, Vol X (15 September 1904), p. 153.
