How do Swiss trains go uphill?

Switzerland is Home to the Steepest Cogwheel Train The country's Mount Pilatus is home to the world's steepest cogwheel railway, which is essentially a traditional train fitted with a rack and pinion system, or cogwheel, enabling it to climb much steeper grades.

The trains of cog, or rack, railroads, however, can scale steep slopes using a special toothed rail, known as a rack, in the middle of the track. The train has a cog that meshes with the toothed rail. As the cog turns, it hauls the train slowly up the slope.

A train has a system called Wheel Slip Protection (WSP). This system automatically eases power to the drive wheels to prevent slipping. A train carries sands that can be distributed in front of the drive wheels giving them some friction to adhere to. This can be operated by the WSP or manually by the driver.

Conventional trains, using steel wheels on a steel track, could never efficiently climb a track as steep as most funicular railways. Steel wheels are used to decrease rolling resistance, which improves the efficiency of trains on flat ground, but would hinder their ability to get traction going up steep slopes.

Description. Gelmerbahn in the canton of Bern, Switzerland, is the steepest funicular in Europe. It has an inclination of up to 106% and a 1,028m (3,373ft) long track. It takes you to the Gelmer Valley 1860m (6,102ft) above sea level, where you can enjoy some spectacular views.

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%.

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.

The Pilatus Railway (German: Pilatusbahn, PB) is a mountain railway in Switzerland and the steepest rack railway in the world, with a maximum gradient of 48% and an average gradient of 35%.

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.

MORE DETAILS

The outer rail is raised to tilt the train to the inside of the curve - this provides roll-over protection and at cruise speeds gravity helps keep the train more or less centered in the track. The wheels are tapered and 'steer' the bogies away from the rails, so on a curve the train is 'steered' around the bend.

Yes. Yes it is easy to walk on top of or inside a train [on the footwalk- if it is moving fast, there will be wind]. It's easy to walk on a moving ship [on calm seas!] It's even easy to walk on the Concorde zipping along at Mach two.
