A year after Manning Wardle supplied this Lancashire short line with a rather mundane 0-6-0T, the builder supplied what would be the only 2-6-0T to run on a British railway. Moreover, its valve gear was a Walschaert variant used on only few locomotives. It was a bulky, frankly unattractive locomotive. Its long side tanks rode high on the boiler in casings pierced at the running board level by long slots, presumably to improve access to the machinery. The leading truck rolled in a truck sited ahead of the smokebox and the cab had large portholes in the weatherboard.
