The Carmarthen and Cardigan Railway was a 7 ft 1⁄4 in broad gauge railway line in Wales that was intended to connect Carmarthen on the South Wales Railway with Cardigan. In fact, it was unable to raise the necessary capital and was loss-making from the time of opening the first short section of its line in 1860, and it was in receivership for much of its life. It eventually reached Llandysul in 1864 but was not extended further during its independent existence.

The Cornwall Railway was a 7 ft 1⁄4 in broad gauge railway from Plymouth in Devon to Falmouth in Cornwall, England, built in the second half of the nineteenth century. It was constantly beset with shortage of capital for the construction, and was eventually forced to sell its line to the dominant Great Western Railway.
