History
The tunnels are on the Abergavenny to Brynmawr railway. The original was built upon Baileys Tramway which ran from ironworks at Nantyglo to the Govilon wharf of the Brecon and Abergavenny Canal.
This was converted to a locomotive-hauled railway and in 1862 the line opened from Abergavenny to Brynmawr. In 1877 the line was doubled, and new tunnel bores at Clydach and Gellifelen were made. The new tunnels are the southerly tunnels.
Both tunnels are connected by an adit as the older tunnel is blocked both ends.
The line was closed in 1958
