==Events==
*Approximate date - Britain's longest tramroad tunnel is opened at Pwll du near Blaenavon in South Wales, more than a mile (2400 m) in length. Begun as a mineral adit, at this time it carries a horse-drawn double track plateway of approximately 2 ft (600 mm) gauge carrying material for Blaenavon Ironworks; next summer it will be incorporated in Thomas Hill's Tramroad.
