Four tank engines are known to have worked the Wellsworth and Suddery Railway in the Railway Series.
The Railway Series
It is recorded in The Island of Sodor: Its People, History and Railways that it had four 0-6-0 tank engines of its own. The railway opened in 1870, so most likely at least two of the locomotives possibly date back to this period, though it is not known if they helped build the line or if it was the contractor's locomotives who did that work. All four were still in service by the time of the 1914 grouping, though.
Their fate afterwards is unknown as no further mention of them is made. Based on the advent of the later NWR push-pull trains supplementing the branch line, it might be assumed that they have been either scrapped, relocated or fitted with push-pull equipment.
