Kidwelly Canal Railway
Under Geo. III., c. 173, of June 20th, 1812, powers were given to improve the harbour of Kidwelly and to make a canal and a railway or tramroad from a canal, already made, in the parish of Kidwelly, called "Kymer's Canal," to the Old Castle House in Llanelly, and for one from the east or upper end of Kyrmer's Canal to Pwll-Llygod in Penbrey, together with branches.
It subsequently became part of the Burry Port and Gwendraeth Valley Railway.
