British narrow-gauge slate railways

Narrow-gauge railways were used extensively in the slate industry of Great Britain, especially in Wales. Many quarries had internal tramways, some using many dozens of miles of track. Others had private lines that stretched from the quarry to transhipment points on local railways, rivers, roads or coastal ports.
