Dinmore Tunnel is the name given to two railway tunnels located on the former Shrewsbury and Hereford Railway (S&HR) line between Hereford station and Leominster station. The first tunnel (currently the 'up' tunnel) was built in 1853, with the second tunnel (the 'down' tunnel) being added in 1891.[1] Both are still in use and are jointly the 15th longest tunnels on the former Great Western Railway. To the south of the tunnel was Dinmore railway station,[2] which closed in 1958.[3] They are located just south to the village of Hope Under Dinmore and tunnels under Queen's Wood Country Park & Arboretum.[4]
Construction
When the S&HR was opened in November 1863, it was a single track throughout. However, all infrastructure was made wide enough to accommodate twin tracks throughout apart from the Dinmore Tunnel which, owing to the uncertain rock strata, was left as a single bore. The engineer, Mr Pollard, recommended that if the line were to be doubled, then a second tunnel should be constructed. When the S&HR became a joint line of the London & North Western and the Great Western and West Midland Railways, they pursued the second tunnel option.[5][6]
The tunnels are split-level - the track on the up line to Leominster being at a higher level than the down line to Hereford, both are Шаблон:Convert long[7] and the line speed through both is Шаблон:Convert.[1]
