The top of the track is rounded, and the wheels on the train are also slightly rounded, at any one time there is only the surface area of a dime touching the rail, this along with incredible weight and the flange on the wheel keep the train on the track.

What are the reasons why you are not allowed to stay near a moving train?
if you fall over on the track it will kill you
Are train wheels magnetic?
The wheels on a train are not magnetic. They are steel wheels and the use of steel helps to reduce friction and propel the train forward.
What is the motion of the train on a moving track?
A train travels over a FIXED track not a MOVING track.
How do superconductors increase the speed of trains?
Superconductors allow the train to 'float' on a layer of magnetism. Since there is no friction (as there would be with wheels on a track) - the trains can reach much higher speeds.
When does a train's brakes start exerting force on the train's wheels?
Assuming that the brakes are not "dragging" they start exerting force on the wheels when they are applied by the engineer.
Does a train in motion contact its tracks?
Yes, train wheels remain in contact with the track at all times. The tracks support the weight of the train. They also guide the train. The wheels are shaped such that the train remains balanced on them. Any slight movement of the wheels sideways is automatically corrected so that the wheels remains exactly on the middle of the rails. If the wheels were not in contact with the track, the train would be flying.
How trains wheels stay on track?
The wheels have flanges on the inside edges, they keep the wheels on the rail. The wheels would not stay on the tracks without the flanges.
What does a train engineer steer a train with?
Well a train need not be steered, only the speed needs to be controlled. The train follows the track due to the grooved wheels. Quite right. The wheels are known as 'flanged' wheels- there is a lip that runs around the inside edge. This allows the wheels to be guided by the track & not slipping off. Speed, direction (forward or reverse) & stopping are the three major situations the engineer controls.
How can railway track produce electrical power with train?
the medal from the track can carry electric signals from train signals and other things the medal on the wheels of the locomotive pick up those signal because the wheels are medal so the signals go from the wheels and into the area that the conductor and helper are and so they know what to do when driving the train
Why was the train on Rudolph a misfit toy?
In Rudolph the Red-Nosed Reindeer, the misfit train had square wheels.
What is the different between bus and train?
well a bus has wheels that run on the road and the train runs on a track twice the speed.
Does trains have steering wheels?
They have flanged wheels - so every wheel "steers", but the direction of the train is controlled by the track - thus no "steering wheel" in the cab.
Example of rack and pinion gear?
A train running along a track. The rail is the rack and the wheels are the pinion.
Why does it take longer for a train to slow down than an automobile?
A train, especially a freight train, is a massively heavy vehicle. The difference between stopping a car and a train could be compared to the difference between stopping a rolling golf ball and a rolling boulder. Each set of wheels on a train has it's own brakes, but still, because of the mass of the train, it takes considerably longer to slow a train down. Also, there is less friction on train wheels and track than there is between tire treads and roads. If all the wheels of a train were suddenly stopped and locked, the train would still skid for a very considerable distance on the steel wheels and track, ruining both. == ==
How do bullet trains stay on track?
Gravity, same as any other train.
What train runs without wheels?
Maglev (magnetic levitation) trains run by way of a magnetic field generated by magnets embedded in the track. As such, they have little or no need for wheels.
