Great Little Trains of Wales
The Great Little Trains of Wales is a joint marketing scheme formed in 1970 to promote some of the narrow gauge railways of Wales and encourage visitors to Wales. As well as marketing the railways, the scheme allows visitors to purchase a discount card, allowing reduced rates on all the lines.
As of 2014, there are so far eleven railways in the scheme.
