Help with sound scripting

Each day I'm learning more about NL, I found out that I may do scripts to do several things in the sim, but I need to know programming language and I have NO IDEA how to make a script
I'm working on a themed park that I plan to release in a couple months. One of the coasters I didn't like it to be in the park, so it became a leftover of this park and turned into a solo track. This track I may release it in a weeks, I already have ideas to do the theme and the layout is almost finished
What I want to do is the next:

I want to play a defined sound that comes from a 3d model when the train passes a certain point, these sounds last from 2 to 4 seconds and there might be 3 or 4 sounds along the track.
What do I need to do a script and put a trigger on the track to play that sound?
Is it hard to do it? Do I really need to know programming language?
Is there any pre defined script so I can do that? Are there tutoriarls inside NL to do it?

Excuse my english
Thanx!

Yes triggers are your friend. I would set them up first in preparation. As for the script I jumped into this a while ago but have since forgotten how to do it. I'll dig around and see if I can find anything.

^thanks I'll check it out
