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.
[1] Both are still in use and are jointly the 15th longest tunnels on the former Great Western Railway.
[3] They are located just south to the village of Hope Under Dinmore and tunnels under Queen's Wood Country Park & Arboretum.
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.
