In the 1953 edition of Railway Engineering William H. Hay says "The ruling grade may be defined as the maximum gradient over which a tonnage train can be hauled with one locomotive....The ruling grade does not necessarily have the maximum gradient on the division. Momentum grades, pusher grades, or those that must regularly be doubled by ...
These include simple rail adhesion, rack railways and cable inclines (including rail mounted water tanks to carry barges). To help with braking on the descent, a non-load-bearing "brake rail" located between the running rails can be used, similar to the rail used in the Fell system, e.g. by the Snaefell Mountain Railway on the Isle of Man.
Hillclimbing is a problem faced by railway systems when a load must be carried up an incline. While railways have a great ability to haul very heavy loads, this is only possible when the tracks are fairly level. As soon as the gradients increase, the tonnage that can be hauled is greatly diminished.
Fitted with Fell center rail but was not used for motive power, but only braking; 3.6% (1 in 27) – Ecclesbourne Valley Railway, Heritage Line, Wirksworth, Derbyshire, UK; 3.6% (1 in 28) – The Westmere Bank, New Zealand has a ruling gradient of 1 in 35, however peaks at 1 in 28; 3.33% (1 in 30) – Umgeni Steam Railway, South Africa [24]
Turkey has a state-owned railway system built to standard gauge (1,435 mm (4 ft 8 + 1 ⁄ 2 in)) which falls under the remit of the Ministry of Transportation and Infrastructure. The primary rail carrier is the Türkiye Cumhuriyeti Devlet Demiryolları (TCDD) ( Turkish State Railways ) which is responsible for all long-distance and cross-border ...
In that case, the resultant force (aggregate gravitational and centrifugal force) exerts on the outside rail more than the inside rail, in which it creates lateral acceleration toward the outside of the curve (which could lead to tipping or derailing). In order to reduce cant deficiency, the speed can be reduced or the superelevation can be ...
The Pilatus Railway is the steepest rack railway in the world, with a maximum gradient of 48% and an average gradient of 35%. Functioning of the rack and pinion on the Strub system. A rack railway (also rack-and-pinion railway, cog railway, or cogwheel railway) is a steep grade railway with a toothed rack rail, usually between the running rails.
The Konya–Yenice railway (Turkish: Konya-Yenice demiryolu) is a 344.7 km (214.2 mi) long, partially electrified railway in southern Turkey. The railway is a major route connecting Turkey's Mediterranean coast to the Anatolian interior as well as the only railway line through the Taurus Mountains .
