Colwall Tunnel actually refers to a pair of tunnels which run through the Malvern Hills. The first was constructed between 1856 and 1861, and remained open until 1926, when a more modern partner was built alongside it. The old tunnel was later repurposed during the Second World War to act as a storage depot for Admiralty munitions. The second tunnel was built between 1924 and 1926 and remains in use to this day. Spanning 1,567 yards, the Colwall tunnels remain some of the longest tunnels on the British railway network.
The eastern portal of the two tunnels lies around a short bend south of the old Malvern Wells (GWR) station, while the western mouth of the tunnels emerges shortly before the present-day Colwall station. This bend makes the eastern tunnel entrance difficult to see from anywhere except the hills directly above it, or a public footpath which cuts under the line just before the tunnel entrance.
