Stewart & Lloyds 0-6-0 Locomotives in Great_Britain
Class Details by Steve Llanso of Sweat House Media
Class Colwyn (Locobase 4868)
These saddle-tankers served Stewart and Lloyds until the end of steam at that iron-ore railway in 1969. Additional information and data from [
] (15 February 2004). This site says that the design was supplied by several builders over many years and was drawn originally from a Manning Wardle locomotive.
