Allt-y-Cefn Tunnel - The Carmarthen and Cardigan Railway (1860-1952)
This tunnel is a feature along the old branch line which was meant to connect the two towns in its title, but never happened due to financial issues. Trains began operating on the line from 1860.
The 167 yard tunnel opened in 1864 near the old Pontre Court platform, this 153 metre structure is a curved build with horseshoe shaped portal entrances lined with brick and masonry.
Passenger trains ceased in 1952 and goods trains followed 20 years later in 1973, since then the tunnel and the line were left abandoned after the track was ripped up a few years later. The tunnel itself is still in very good condition and very dry inside with the remains of old cable posts along the walls.
A nice little explore on our Wales holiday.
