Can a train go downhill?

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%.

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. The train has a cog that meshes with the toothed rail.

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.

Long trains take longer time to stop than a single car because the braking effort is not synchronized.

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.

Try to limit all your grades to 1.8%, unless you really want some interesting (or aggravating) operations to be required. 4% is an absolute maximum... real railroad have very smooth, gradual changes in elevation, your model railroad will look best if it does the same.

Trains cannot collide with each other if they are not permitted to occupy the same section of track at the same time, so railway lines are divided into sections known as blocks. In normal circumstances, only one train is permitted in each block at a time. This principle forms the basis of most railway safety systems.
