Llynvi and Ogmore Railway
originally Duffryn, Llynvi and Porthcawl Railway
Llynvi and Ogmore Railway (originally the Duffryn, Llynvi and Porthcawl Railway) was formed by the merger on 1 July 1866 of the broad-gauge Llynvi Valley Railway and the standard-gauge Ogmore Valley Railway. It served Porthcawl, Bridgend, and Tondu in Glamorgan, Wales, along with various branches.
The company name was spelt
Llynvi using the Anglicised phonetic spelling popular at the time, rather than the correct Welsh . Llynfi

Locomotives [ edit ]
Broad gauge 0-6-0ST [ edit ]
The railway owned two
0-6-0STs for goods traffic. Built by Slaughter, Grunning and Company, they were similar to the South Devon Railway Dido class built at around the same time. 
In 1868 they were exchanged for
standard gauge locomotives from the West Cornwall Railway, which had recently been rebuilt to allow broad gauge trains to run through from the Great Western Railway to Penzance.
Ada and Una became GWR 2146 and 2147 respectively. They were withdrawn in 1884 and 1886.
Broad gauge 4-4-0ST [ edit ]
The railway owned a single
4-4-0ST passenger tank locomotive. Built by Slaughter, Grunning and Company, it was similar to the South Devon Railway Eagle class.
Rosa was also exchanged for West Cornwall Railway rolling stock in 1868. It was then rebuilt as an 0-6-0ST, making it similar to Ada and Una.
It became GWR 2145 and was withdrawn in 1885.
Standard gauge [ edit ]
Twelve Lynvi and Ogmore Railway locomotives were acquired by the Great Western Railway in 1873 and renumbered 915 to 926.
