Midland & South Western Junction No 5 to 7
Great Britain 1882 3 produced
Starting in 1882, this joint railway operated three tank locomotives with a 2-4-0T wheel arrangement for use with passenger trains. These were a standard Beyer, Peacock & Co. design with five and a half foot diameter driving wheels. Number 6 is recorded as later being sold to the Wight Central Railway. In 1884, a slightly larger machine from the same manufacturer followed, bearing the number 8.
