The Great Little Trains of Wales (Welsh: Trenau Bach Arbennig Cymru) is the name of a joint marketing scheme formed in 1970 to promote some of the narrow gauge railways of Wales and encourage visitors to Wales.
[1] As well as marketing the railways, the scheme allows visitors to purchase a discount card, allowing reduced rates on all the lines.
As of 2021, there are twelve railways in the scheme.
