While looking at the map around Clifton Suspension Bridge something else of interest sprang off the page. In Sion Hill a little south of the suspension bridge was marked “Clifton Rocks Railway”. Searching the web revealed a disused funicular railway. In a tunnel. I had to go and have a look obviously.
The tunnel is 500 feet long rising 240 feet at a gradient of 1:2.2. Semi-elliptical and lined with bricks it is 27 feet 6 inches wide andv18 feet high with two pairs of tracks allowing operation of four cars, in pairs connected by steel cables.
The cars were raised and lowered by means of adding or removing water from tanks under the car floors to balance the weight of car, passengers, and water tank so that the upper car going down pulled the lower car up the incline.
The railway was very popular on opening but that didn’t last and in 1908 it went into receivership, being purchased by the Bristol Tramway and Carriage Co.
That rather heralded or at least hastened the end for the operation of the Clifton Rocks Railway and in 1934 it ceased operations.
At the outbreak of the Second World War the Ministry of Works and Buildings leased the tunnel from the Tramways Company. In March, 1940. British Overseas Airways built an office suite and used part of the upper tunnel for storage. The ARP (Air Raid Precaution) Committee established air raid shelter number 1898.
In 1941 the four cars which had remained at the bottom of the tunnel since the railway closed were removed and the BBC moved in. They built a complex in the tunnel of four main chambers and three smaller rooms in the bottom station. From the top these contained transmitters, a studio for creating programmes, a recording room to record programmes which also contained enough recorded material for several weeks’ broadcasting, and a control room where eighty GPO land lines to other BBC sites could be switched. ![](https://lh5.googleusercontent.com/nRqi4fLmBi49PJkSsoU_z4Y2UPAlbKxlVFr9VDxM3GhZCZ6H3bvCn1itj_A)
The three small rooms contained generators, ventilation plant, and of course a canteen because you can’t fight against Lord Haw-Haw without plenty of tea.
In the event the main BBC Bristol studios were never put out of action by the German bombing so the emergency studio at Clifton was never needed but the useful control room alone made the tunnel conversion worthwhile. The BBC continued to make use of the site until 1960 when advances in radio technology rendered it redundant.
The information above is just a brief summary of that supplied by Richard Hope-Hawkins on the excellent Cliff Rocks Railway website which is well worth visiting if you want to know more. You can also book tours via that site when they are running. I do hope they manage to open the site properly as a tourist attraction, given its proximity to the suspension bridge it surely has great potential.
