Chipping Sodbury Tunnel

Chipping Sodbury Tunnel is a railway tunnel that sits on the South Wales Main Line in England. It was constructed around 1900 for the South Wales and Bristol Direct Railway and runs some 2 ¹⁄₂ miles (4.0 km) west of Badminton railway station and Chipping Sodbury Yard.

The tunnel is constructed with an arch brick lining and measures some 27'6" across and 20'9" high. It slopes at a 1:300 gradient from Badminton falling in a westerly direction towards Chipping Sodbury.

The tunnel is prone to flooding and it is estimated that the route via the tunnel is closed an average of 24 times per annum, resulting in the cancellation and diversion of 50 passenger services and 40 freight services.
