Fell Mountain Railway System
The Fell system was the first third-rail system for mountain railways that were too steeply-graded to be worked by adhesion on the two running rails alone. It uses a raised centre rail between the two running rails 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. Extra brake shoes are fitted to specially designed or adapted Fell locomotives and brake vans, and for traction the locomotive has an auxiliary engine powering horizontal wheels which clamp onto the third rail. The Fell system was developed in the 1860s and was soon superseded by various types of Rack railway for new lines, but some Fell systems remained in use into the 1960s. The Snaefell Mountain Railway still uses the Fell system for (emergency) braking, but not for traction.

Famous quotes containing the words fell, mountain, railway and/or system:
“I gave him the lead gift in the twilight. What fell was relaxed,
Owl-downy, soft feminine feathers; but what
Soared: the fierce rush: the night-herons by the flooded river cried
fear at its rising
Before it was quite unsheathed from reality.”
—Robinson Jeffers (1887–1962)
“Tjaden: How do they start a war?
Albert: Well, one country offends another.
Tjaden: How could one country offend another? You mean there’s a mountain over in Germany gets mad at a field in France?”
—Maxwell Anderson (1888–1959)
“Her personality had an architectonic quality; I think of her when I see some of the great London railway termini, especially St. Pancras, with its soot and turrets, and she overshadowed her own daughters, whom she did not understand—my mother, who liked things to be nice; my dotty aunt. But my mother had not the strength to put even some physical distance between them, let alone keep the old monster at emotional arm’s length.”
—Angela Carter (1940–1992)
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
