Gradients in railway
WebGrade or Gradient is the ratio of vertical rise or fall of the road center line with respect to its length. It has to be provided for the vertical alignment of the road. When we provide gradient to the road, vehicle has to apply more power to overcome the component of the gravity force. More the grade more effort it required. WebGradient In Railway-Ruling The ruling gradient is the steepest gradient that exists in a section. It determines the maximum load that can hauled by a locomotive on that section. While deciding the ruling gradient of a section, it is not only the severity of the gradient, but also its length as well as its position with respect to the gradients ...

WebMetros and pure commuter railways often also allow steeper gradients, over 4%, for the same reason. High-speed railways commonly allow 2.5% to 4% because the trains must be strong and have many wheels with power to reach very high speeds. For freight trains, gradients should be as gentle as possible, preferably below 1.5%.
