The Glyn Valley Tramway was a narrow gauge railway that ran through the Ceiriog Valley in north-east Wales, connecting Chirk with Glyn Ceiriog in Denbighshire (now Wrexham County Borough). The gauge of the line was while it was horse-drawn, which was unofficially increased to when steam locomotives were introduced. The total length of the line was , of which were worked by passenger trains, the remainder serving a large granite quarry and several minor slate quarries. Route Quarries served History The original route The railway was built to connect the quarries at Glyn Ceriog with the Shropshire Union Canal at Chirk. A standard gauge "Ellesmere & Glyn Valley Railway" was authorised by an Act of 6 August 1866 to run from the Cambrian Railway at Ellesmere to the GWR at Chirk and thence to follow the Glyn Ceiriog road to the quarries. No construction took place and by an Act obtained in 1869, the Ellesmere to Chirk portion was abandoned. A further Act of Parliament, obtained on 10 August 1870, allowed the original company to be dissolved, and the Glyn Valley Tramway to be incorporated to take over the rights, assets and goodwill of the previous company. The company believed it could not raise the £120,000 capital required to build the standard gauge line. Henry Dennis suggested a narrow gauge line instead, which would only require £25,000. The line would run from the canal at Chirk Bank to the Cambrian Slate Quarries. This initial line, at long, was opened in 1873, and was worked by horse and gravity traction carrying passengers and freight. Rebuilding and extension In 1885, additional parliamentary powers were obtained to abandon the Quinta Tramway section between Pontfaen and Chirk Bank, replacing it with a new line from Pontfaen to the Great Western Railway's Chirk station. A two-mile extension was also authorized from Glyn to the quarries around Pandy. At that time, Henry Dennis was a director and also the tramway's Engineer. He was also the Engineer for the Snailbeach District Railways, near Shrewsbury. When rebuilding of the line began in 1887, Dennis offered to loan the two steam locomotives from Snailbeach, as the carriage of lead ore on that railway had plummetted. They were of the slightly narrower gauge of , and the difference meant that they derailed very easily. The Act of Parliament did not allow the gauge to be changed as part of the
