The Ruabon Brook Tramway (also known as Jessop's Tramway, and in its later years as the Shropshire Union Tramway) was a Welsh horse-drawn tramway linking the Ruabon coalfield to the Ellesmere Canal at Froncysyllte, with a private extension into the Monsanto works at Cefn Mawr which reconnected to the main line at Trevor.[1] The area was rich in coal, clay and minerals, and this was part of an extensive network in the Ruabon, Minera and Brymbo areas..
