The Teifi Valley Railway (Welsh: Rheilffordd Dyffryn Teifi) is a 2 ft (610 mm) narrow gauge railway occupying a section of the former standard gauge Great Western Railway line between Llandysul and Newcastle Emlyn. After the closure of the former line by British Rail in 1973, a preservation group built and periodically extended a narrow-gauge railway along the route, westwards from Henllan, eventually operating a 3 kilometres (1.9 mi) long line as a tourist attraction.
