Red Marble Grade, Topton, North Carolina. A 2015 survey [12] lists the 3.5 mile stretch between MP 87 and MP 90.5 at a 4% average grade and says there are isolated stretches approaching 7%. When originally built the ruling grade was 4.2% as listed by southern railway. But due to the fills settling it has drastically changed. [12]
Trains would leave Sparks with enough engine to manage the 0.43% grade (e.g. a 2-10-2 with a 5500-ton train) and would get helper engines at Wells; the "ruling grade" from Sparks to Ogden could be considered 0.43%. But nowadays the railroad doesn't base helper engines at Wells so trains must leave Sparks with enough power to climb the 1.4% ...
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 ...
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 ...
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 ...

Common rail fuel system on a Volvo truck engine. In 1916 Vickers pioneered the use of mechanical common rail systems in G-class submarine engines. For every 90° of rotation, four plunger pumps allowed a constant injection pressure of 3,000 pounds per square inch (210 bar; 21 MPa), with fuel delivery to individual cylinders being shut off by valves in the injector lines.
