Data from "Locomotives of the Wrexham, Mold & Connah's Quay Ry," The Locomotive Magazine, Vol X (15 October 1904), p. 181. Hudswell works numbers were 1-2.
The 25-mile W M & C Q was a bridge or transfer line connecting the Birkenhead side of the Mersey estuary with the Cambrian Railways system to the north. It became the heir to the two locomotives shown here when the 6-mile Buckley & Connah's Quay was leased to the larger railway.
Named Wheatley & Kenyon, both were frequently modified and overhauled; Locobase believes the data in the specs date from the late 1890s when both were overhauled. It is possible, however, that the data refer to the original H C engines - the wording is imprecise.
NB: The direct heating surface (including the firebox heating surface) is an estimate calculated by subtracting the calculated tube heating surface from the reported total evaporative heating surface.
Data from "Locomotives of the Wrexham, Mold & Connah's Quay Ry," The Locomotive Magazine, Vol XI (15 May 1905), p. Works number was 2157.
When the Brymbo branch was opened in 1883, the W M & CQ needed a new freight (goods) locomotive to serve the collieries on that line. This B P locomotive went into service as the Emily, but was later renumbered 10.
