Balsam Mountain Grade, Balsam N.C. Balsam Mountain, home of highest railroad station east of the Rockies; average grade about 4.0%, max 4.5%. 1 of 2 grades on southern railways former Murphy branch that are +4% grade. Balsam Mountain has seen many runaways. It is still in service operated by the Blue Ridge Southern Railroad . 1 in 22 (4.5%)
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 ...
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 ...
A steep grade railway is a railway that ascends and descends a slope that has a steep grade. Such railways can use a number of different technologies to overcome the steepness of the grade. Such railways can use a number of different technologies to overcome the steepness of the grade.
Saluda Grade was the steepest standard-gauge mainline railway grade in the United States. [1] Owned by the Norfolk Southern Railway as part of its W Line, Saluda Grade in Polk County, North Carolina, gained 606 feet (185 m) in elevation in fewer than three miles (4.8 km) between Melrose and Saluda, North Carolina. Average grade was 4.24 percent ...
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.
It is the second-steepest rack railway in the world, after the Pilatus Railway in Switzerland, [3] with an average grade of over 25% and a maximum grade of 37%. The railway is approximately 3 miles (5 km) long and ascends Mount Washington's western slope, beginning at an elevation of approximately 2,700 feet (820 m) above sea level and ending ...
The average grade of the line would be 12% but would top out at 25%. Normal trains can not retain traction on the rails at grades steeper than 10%, so the railway would need to use a cog and rack system to help pull trains up the mountain and control the speed of the descent.
