- Fell mountain railway system
The Fell system uses a raised centre rail between the two running rails on steeply-graded railway lines to provide extra traction and braking, or braking alone. Trains are propelled by wheels or braked by shoes pressed horizontally onto the centre rail, as well as by means of the normal running wheels. These horizontal wheels and shoes are fitted to specially designed or adapted Fell locomotives and brake vans.
History
The Fell system was designed, developed and patented by British engineer
John Barraclough Fell . The first test application was alongside theCromford and High Peak Railway 's cable-hauled incline atWhaley Bridge inDerbyshire , England, in 1863 and 1864.These tests attracted the attention of the French Government, which conducted its own tests on the slopes of
Mont Cenis in 1865. As a result, the Mont Cenis Pass Railway was built as a temporary connection betweenFrance andItaly whilst the tunnel under the Alpine pass was being built.A list of Fell railways
The following railways have used the Fell system. Of these, the only one still in operation is the electrified
Snaefell Mountain Railway on theIsle of Man , which occasionally uses the centre rail for braking only - the cars are all now equipped with rheostatic braking, which meets all normal braking needs. The only surviving Fell locomotive, New Zealand Railways H 199, is preserved at theFell Engine Museum ,Featherston ,New Zealand , near the site of theRimutaka Incline .Brazil
*The
Estrada de Ferro Cantagalo (Cantagalo railway) from Niterói to Nova Friburgo opened in 1873. Brazil's first mountain railway, of 1100 mm gauge, it re-used some of the equipment from the Mont Cenis Pass Railway, and continued in operation until the 1960s.France
*The Chemin de Fer du Puy de Dôme at
Clermont-Ferrand opened in 1907 and closed in 1926. It usedcompressed air to force the wheels against the centre rail.
*The Mont Cenis Pass Railway on the border withItaly was 77 km (48 miles) long and ran from 1868 until superseded by a tunnel under the pass in 1871.Isle of Man
*The
Snaefell Mountain Railway opened in 1895. It uses electricrailcar s, with a Fell rail for braking.New Zealand
*The Rewanui Incline on the West Coast of the South Island used a Fell rail for braking from its opening in 1914 to 1965. It closed in 1985.
*TheRimutaka Incline nearFeatherston on the North Island opened in 1878 and closed in 1955. It was replaced by the long Rimutaka tunnel.
*The Roa Incline on the West Coast of the South Island used a Fell rail for braking from its opening in 1909. It closed in 1960.
*TheWellington Cable Car used a Fell rail for emergency braking from its opening in 1902 until 1978, when it was upgraded.*Expand list|date=August 2008
Renewals
Ten kilometres of new Chinese manufactured Fell rail was expected to be delivered to the Snaefell Mountain Railway in December 2006 for track-laying between the 2006 and 2007 seasons (Railway Magazine, February 2007).
