Model animation—bringing models to life—adds enormously to the interest and enjoyment of any layout or individual model! In this installment I want to touch on more “points” on lighting and LEDs—likely more than you’ll ever want to know!

heys guys this is my second post to the site i model the lamoille valley a short line in the very north of vermont. the LVRC as it was known hasn't been around since the mid 1990s but it as a interesting railroad. i did a few engine 2 high nose one chop nose and the other two we done by mike macnamara of south jersey workshop  great work he does i just wanted to who else did some custom work of there short lines.

I have just finished installing a Tsunami decoder in an old Atlas UP FP7 model that I have had since I was a teenager. It is number 1498. I am starting to program the sound and lights and I wasn't sure what air horn would be appropriate for this model given the prototype. I don't even know where to find this sort of prototype information. Any help would be appreciated.
Thanks.
