There's a word for what you're asking for-- onomatopoeia. Many times editors would rather you not use the sounds, but describe it, unless you're writing a PB or even early chapter book. I wrote about a train in one of my short stories. As a train gets closer, it makes a rumbling sound. As it leaves the station, it makes a steadily increasing chugging sound. The whistle sounds like a forlorn call in the night. The brakes hiss and screech when the train slows down to a stop. If you don't have a train nearby to listen to, go online and do a search.
The sound is then magnified by the shape of the horn. Large truck horns make a very loud noise because the sound is made by passing compressed air through the sounding device. A claxton horn makes a sound that resembles the word A-hoo-gah.air cleaner horn or air horn.
