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.
Depends on whither you count not having wheels as different. Outer, upper shape is not different.
The weight of a train engine varies depending on the type of engine. A diesel engine can weigh as much as 250 tons while a steam engine would be about 100 tons.

a electric train is faster than a steam engine
A couple are the engine the cars wheels and the horn.
The power train transfers power from the engine to the wheels.
Each car has 8 wheels.
drive train
5000
a car has 4 wheels and the train carrys 100 people or more
You find the 4x4 engine in a vehicle that has a drive train that allows all the four wheels to receive the torque from the engine.
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.
A typical train has wheels and rolls on metal rails. It's drive wheels are driven by a steam engine, a Diesel engine, or even electric motors powered by the rail system or overhead wires. An electromagnetic train, on the other hand, does not ride on wheels, or have an engine, per se. It is suspended from it's track by a powerful magnetic field generated by electro-magnets in the track and train. In addition to providing suspension of the train, the magnetic fields are used to propel the train itself, so it does not need an "engine" at all.

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.
