Brymbo (aka Brake) tunnel was closed in 1862 - not long after it had opened - when a 'normal' gradient line was extended down the valley from the Broughton Hall Ironworks, thus avoiding a rope worked incline of 1 in 3.5. A chapel was built over the trackbed near the tunnel entrance in 1885.

The nearby 220-yard Summerhill tunnel is buried at its eastern end. Structurally, it's in appalling condition. Sections of roof have parted company and there is considerable bulging of the walls. A catastrophic collapse must surely occur soon. You are strongly advised not to enter this tunnel.
