2.5% to 4%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%.
What is the maximum incline of a train?
Grades are generally 1 percent or less, and grades steeper than about 2.2 percent are rare. The steepest grade on a major railroad's main track was historically said to be on the Pennsylvania Railroad north of Madison, Indiana, rising 413 feet over a distance of 7012 feet — a 5.89-percent grade.
Why can’t trains go up hills?
Trains face difficulties going uphill because the gradient adds to the drag caused by their weight, while the tractive force remains constant. Trains going uphill face the challenge of concentrated braking force in a small area, which can lead to the train running away on steep inclines or slippery rails.
How much of an incline can trains go up?
How steep is the incline railway?

Can trains go through mountains?
A mountain railway is a railway that operates in a mountainous region. It may operate through the mountains by following mountain valleys and tunneling beneath mountain passes, or it may climb a mountain to provide transport to and from the summit.
