Extremely steep gradients require the use of cables (such as the Scenic Railway at Katoomba Scenic World, Australia, with a maximum grade of 122% (52°), claimed to be the world's steepest passenger-carrying funicular [15]) or some kind of rack railway (such as the Pilatus railway in Switzerland, with a maximum grade of 48% (26°), claimed to ...
Typically on straight road sections, the drainage gradient is at least 1–3% due to the normal cross slope of 1–3%. In curved sections the drainage gradient is higher, and may often reach 5–12% due to superelevated CS that may reach 5–8% in areas with icy roads and up to 12% in areas without icy roads.
Sand Patch Grade is an approximately 100-mile-long (160 km) section of railroad track known for its steep grades and curves through the Allegheny Mountains of Pennsylvania and western Maryland. [1] Dropping over 1,000 feet (300 m) in about 20 miles (32 km) and with grades as much as 2%, [ 2 ] Sand Patch Grade is one of the steepest railroad ...
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 trains are fitted with one or more cog wheels or pinions that mesh with this rack rail.
Sag vertical curves are curves which, when viewed from the side, are concave upwards. This includes vertical curves at valley bottoms, but it also includes locations where an uphill grade becomes steeper, or a downhill grade becomes less steep. The most important design criterion for these curves is headlight sight distance. [2]
Platte Clove, sometimes Plattekill Clove, is a narrow and steep valley in the Catskill Mountains of New York. ... It has an average grade of 12% over 1.6 miles, ...
Equipped with a 2.75 continuous Hp motor, this treadmill offers the industry standard speed of up to 12 MPH and an incline of up to 12%. Much like other models in the NordicTrack treadmill, this ...
The Mt. Washington Road Race has an 11% grade, averaged over 7.6 miles. The Mount Washington Road Race is a 7.6-mile (12.2 km) road running event that follows the auto road going from the base of Mount Washington in New Hampshire nearly to the mountain's summit (located at 6,288 feet (1,917 m) above sea level). The race was first held in 1936 ...
