Today it is the world's only preserved operational 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge cable railway system. The Cromford and High Peak Railway opened in 1831 with grades up to 1 in 8. There were nine inclined planes: eight were engine-powered, one was operated by a horse gin.
It remained powered by a steam engine up until it was taken for renovation in 1968. [19] Until the end of the 1870s, the four-rail parallel-track funicular was the normal configuration. Carl Roman Abt developed the Abt Switch allowing the two-rail layout, which was used for the first time in 1879 when the Giessbach Funicular opened in ...
In any given country, rail traffic generally runs to one side of a double-track line, not always the same side as road traffic. Thus in Belgium, China, France (apart from the classic lines of the former German Alsace and Lorraine), Sweden (apart from Malmö and further south), Switzerland, Italy and Portugal for example, the railways use left-hand running, while the roads use right-hand running.
Presby assumed direct management control of the railway in December 2017. In 2021, the railway completed two of the largest improvement projects in its history. The existing 25 lb/yd (12.4 kg/m) rail was replaced with 100 lb/yd (49.6 kg/m) rail and a new 34,000 sq ft (3,159 m 2) maintenance facility was completed. The new facility enabled the ...
The line is 4.6 km (2.86 mi) long, [6] climbs a vertical distance of 1,629 m (5,344 ft), and is of 800 mm (2 ft 7 + 1 ⁄ 2 in) gauge. [ 7 ] [ 8 ] [ 9 ] Because of the rack-system, there are no conventional points or switches on the line, only rotary switches (see photograph) and traversers .
The uphill journey takes around 290 minutes (4.8 hours), and the downhill journey takes 215 minutes (3.6 hours). It has the steepest track in Asia with a maximum gradient of 8.33%. [3] During Meter Gauge era in 1990s, The Nilgiri Express used to run between Chennai(then Madras) & Udhagamandalam(then Ooty) directly.
A unique demonstration electrically powered suspension line was built by the Scottish engineer George Bennie near Glasgow. Two propellers delivered 240 horsepower (180 kW) in a short burst for acceleration to the cruise speed of 160 km/h. [3] It was not a true monorail as it used an overhead running rail and a guide rail below.
Where the line is too steep to rely on adhesion for climbing, a rack railway may be used, in which a toothed cog wheel engages with a toothed rack rail laid between the tracks. A now little used alternative to the rack and pinion railway is the Fell system , in which traction and/or braking wheel are applied to a central rail under pressure.
