In steam and combustion engines, thermal energy is changed to mechanical energy.
Either heated gas or heated fluid is created that exerts force to turn the engine. In combustion engines, chemical energy becomes thermal energy which becomes mechanical energy.
In electrical engines (motors), electrical energy is changed to mechanical energy by the manipulation of magnetic fields.
In the engine of a typical train, the energy transformation that takes place involves converting the chemical energy stored in fuel (such as diesel) into mechanical energy through combustion. This mechanical energy is then used to move the train by powering the wheels.

What energy transformations take place in:
light energy is changed into chemical energy.
When sunlight strikes a house, the energy transformation that takes place is from radiant energy (sunlight) to thermal energy (heat). The house absorbs the sunlight, which then gets converted into heat energy, warming up the interior.
Kinetic energy
The energy transformation that takes place is the conversion of one form of energy to another, such as kinetic energy to thermal energy, electrical energy to light energy, or chemical energy to mechanical energy. This conversion is governed by the laws of thermodynamics and is essential for all processes and activities in the universe.
All most all trains are diesel/electric, an diesel engine turns a generator that powers electric/traction motors.

When fuel is used by an engine, the chemical energy stored in the fuel is converted into thermal energy through combustion. The thermal energy is then used to produce mechanical energy that powers the engine, ultimately moving the vehicle or performing work.
In a generator, mechanical energy from a rotating turbine or engine is converted into electrical energy through the process of electromagnetic induction. The movement of a magnetic field relative to a conductor creates an electric current, resulting in the transformation of mechanical energy into electrical energy.
