A train goes twice as fast downhill as it can go uphill, and 2/3 feet as fast uphill as it can go on level ground.

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.
They can, but only gradually. You see, trains don't have good traction on the rails like cars do on roads, it's steel on slippery steel. On a bad incline, one wrong move can cause an entire train to slide downhill out of control. Train can indeed go uphill.
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%.
Most trains find it difficult to climb hills and mountain slopes. 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.
Reduced traffic: During the nighttime, there is generally less road traffic and fewer other trains on the tracks. This allows trains to move more efficiently and with fewer delays, as they encounter fewer obstacles and can maintain a consistent speed.
The Glacier Express is the world's slowest train, taking more than eight hours to travel between Zermatt and St. Moritz in Switzerland at an average of 18mph. Along the way, it passes over nearly 300 bridges, travels through 91 tunnels and takes in endless stunning Alpine views.
Switzerland is Home to the Steepest Cogwheel TrainThe 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.
If the train is heading in the direction in which the locomotive end of the train is facing, this is considered 'pulling'. If the train is heading in the opposite direction, this is considered 'pushing' and the motorman or engine driver is located in the alternative cab.
In the most devastating train derailments, passengers and occupants can be seriously injured if the train's momentum causes it to come off the tracks and topple over on its side or crash into other compartments. Some derailments have surprisingly minor implications.
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.
The world's steepest cogwheel railway goes up the PilatusThe steepest cogwheel railway in the world, with a gradient of 48% and a length of 4'618 metres, links Alpnachstad with Pilatus Kulm at an altitude of 2'132 m.
