A gradient of, for example, 1 in 45 means there is 1 unit of fall (or rise) for every 45 units of run. That could be 1 metre of fall over 45 metres of run, or 1 inch of fall over 45 inches of run, or 1 mile of fall over 45 miles. Gradient ratios are dimensionless, so as long as the units of rise/fall and run are the same ...

WebGradient averaging Acceleration due to gravity is 9.79mg 2 Using V 2 = U 2 + 2aS, the speed of the train and the average gradient G, the Braking Distance is: G = 1500/( 12e0/50 +300/ … WebJan 31, 2024 · The track grade is expressed as the percentage of its rise for the length of its run. For example, if you have 100 inches of model railroad track and the train climbs one inch, then the grade is 1 percent. When 25 inches of track rises 1 inch, the grade is 4 percent. The maximum grade is the steepest slope your trains can climb.
