How steep of a hill can a train climb?

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.

Since 1889 from Alpnach and up the Pilatus Commissioned in 1889, a gradient of up to 48 percent, about 30 minutes travel time: that is the steepest cogwheel railway in the world in figures.

In normal slope of track (say 1:3), the train driver use brakes and control the down hill fast travel. If the slope is abnormal, the track will have additional rack type rail. The train will have a pinion wheel and it will be moving on the rack, the wheel will be controlled by breaking system.

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%.

Hillclimbing is a problem faced by railway systems when a load must be carried up an incline. While railways have a great ability to haul very heavy loads, this advantage is only significant when the tracks are fairly level. As soon as the gradients increase, the tonnage that can be hauled is greatly diminished.

Train Tilting Systems Found on both high-speed rail systems and legacy lines, tilt trains are designed to tilt carriages into the curve of the track. The tilting action of the car body compensates for the force experienced by passengers inside, particularly when rounding curves at a high rate of speed.
