I don't know if this is the main reason but, 'the tracks spread out the weight of the train so the wagons do not sink into the ground.'

yes it is formed by heat AND pressure
For a gas, pressure and volume are inversely related. If pressure decreases, volume will increase.
The substance that cools beneath the earths surface when an intrusive igneous rock forms is Magma. Magma is a molten material made up of rocks and minerals.
As water vapor increases, pressure decreases due to the fact that water is made up of hydrogen and oxygen, which is lighter than what most of the air is made out of, oxygen and nitrogen.
No, you must have the same gauge track as your train is made in.
No. There is neither a train nor a light rail around Uluru. Attempts have been made to keep the area as close to its natural state as possible.
A train made from gum is a Chew Chew train get it a CHEW CHEW train.

The First bullet train was made in 1930
The sucker is dish shaped, when pressed against a smooth surface the air is forced from beneath the sucker.The rubber makes an air tight seal and the air pressure outside is greater than the air pressure beneath the sucker, thus forcing the rubber sucker to 'stick'.
A glacier can completely reshape the land. As it is made of very heavy ice, this ice can erode surfaces from the debris and rocks that it carries and the amount of pressure it places on the surface beneath it during its movement.
a mark made by pressure is a print
yes, it is made up of basalt, if that was your question.... ;)
It is made of steel.
The train was made in Indoneisa in 3555
It was made in 1825
