The body of trains is primarily constructed from steel due to its strength, durability, and resistance to wear and tear. Steel is favored for its ability to withstand the stresses of high-speed travel and heavy loads. Additionally, aluminum is sometimes used in train construction for lightweight applications, as it can improve fuel efficiency and reduce overall weight.
Steel.
Centrifugal force is pulling the train's metal wheels against the sides of the metal train tracks, creating friction. Metal on metal makes a horrible noise.

Trains are built with plastic and metal. Electricity is used to run the motor in the train. The train gets the electricity from the track or catenary wire which is connected to the appropriate power supply.
Aluminum.
Yes. Train tracks are metal because if they were wooden such fast moving train wheels will cause friction on the wooden tracks, setting them on fire.
Maybe because if we build a train with non-metal it will not able to carry heavy loads which a train build with metal can easily do
Thorium has no biological role. Thorium is a heavy, radioactive metal which is not used in the human body.
Sheet metal used on older car bodies typically ranges from a gauge of 16 to 18. Sheet metal used on the auto body of new vehicles and when aftermarket body work is performed tends to be between 20 and 22 gauge.
Metal
Trains consists mainly of various steel alloys, although sometimes aluminium gets used for body panels. Then there's copper and possibly aluminium for whatever wiring the train has. Brass for the occasional bushing/bearing.
