Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 20359)

Data from "The Locomotive History of the Cambrian Railways", Locomotive Magazine, Volume XX [20] (14 March 1914), pp. 85-86. Works numbers were 1235-1240 in 1864.

The MWR never actually linked Llanidloes and Llandovery to its west as originally planned (a London & North Western Railway line later accomplished that). Instead, when opened in 1864, its 46.2 miles ran south to southeast from Llanidloes to Builth Wells, then southeast to Three Cocks, where a southwesterly extension took it to Talyllyn.

A twelve-engine order from Kitson used the same boiler and firebox for both, but this passenger sextet had a shorter stroke and taller drivers than the six goods locomotives shown in Locobase 20359. Two were soon sold in 1868 to the Manchester, Sheffield & Lincoln as their 268-269.

The Cambrian ran the trains over the usually financially strapped MWR beginning in 1888 and took over control in 1904.
