Branch lines are often steeper: 3%-5%. Certain special lines such as mining branches may be steeper still. If grades are excessive, locomotives may have trouble pulling cars up the incline. This is true for both model railroads and full-size railroads.

WebOct 9, 2024 · Our model train incline calculator provides an easy way to work out the gradient that you need to implement on your model train layout using the rise and the run. You can also calculate the required incline by manually using the gradient formula that we've covered in this guide. 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%.
