Sounds get higher in pitch as they get closer, due to the sounds waves getting packed closer together. (Which IS higher-pitched)
Sounds get lower in pitch as they go away, due to the sound waves being pulled farther apart than normal. (Which IS lower-pitched). This is called the Doppler effect, and works with light, also.

Why is the pitch of a train's whistle higher as the train approaches and loweras it moves away?
This is known as the Doppler effect. As the train approaches you, the wavelength of the sound waves it emits are compressed, and therefore the whistle sounds higher. When the train is moving away, the wavelengths are extended, causing the whistle to sound lower. If the train were not moving at all, the pitch you would hear from the whistle would be somewhere between the high and low pitches you hear when the train is moving.
Which had higher amplitude?
it is the train whistle
What causes the change in pitch of an approaching train whistle?
sound is wavelengths, and wavelengths get compressed when coming to you (and stretched when going away). the closer the wavelengths, the higher the pitch!
What happens to the sound of a train whistle as the train approaches and then passes?

Would you hear a change in pitch if you are moving on a train and the whistle blows?
The train's whistle can change in pitch over time.

A train passes by blowing its whistle As it passes the sound of the whistle is lower than it was on its way towards you This is due to?
a change in the sound's frequency caused by the motion of the sound's source
When was The Wichita Train Whistle Sings created?
The Wichita Train Whistle Sings was created in 1968.
A train whistle sounded in the distance is train a noun?
Yes. 'Train whistle' is a compound noun, which means that both 'train' and 'whistle' are nouns individually but here they work together. The word 'train' is applied to 'whistle' in the place of an adjective, that is, a word that describes the type of whistle. But have you ever heard a wolf whistle? Many compound nouns eventually run together, like handbook or cupboard, and maybe one day, wolfwhistle.
Imagine you are waiting for a train to pass at a railroad crossing will the train whistle have a higher pitch as the train approaches you or after it has passed you by?
A pleathorea of sounds, just go trackside and listen, from the piercing note of a horn, to the roar of the diesel engine to the click-clack of the wheels on the joints in the rail to the squeal of steel wheel on steel rail, there are hundreds of sounds to enjoy. "Choo Choo" doesn't cut it, sorry. Only the ignorant can agree that any train ever made this sound.
Would you hear a change in pitch if you are moving on a train and the whistle blows?
The train's whistle can change in pitch over time.
