Sori guys and gals.
What I meant was the horns that would be on the models shell as manufactured.

Ok, that is much better.
Your first question comes under the category of, My trains do not work, Whats wrong? ;)
Do some Google searching. It might depend on the railroad preferences. Many railroads had different horn requirements and no doubt some loco manufactures might have had a default horn type that was included with the loco.
With searches, you can usually develop some good links to store in Favorites and increase your modeling knowledge quite a lot.
Ok, I do not have any info about this specific issue but I have found over the past few years, that sometimes I get opinions from others that are not correct. With the search method, I most of the time have correct info.
Yes, you might have to wade though other links that are not really related but then, you never know what you might find.
I use the two below search engines.

Google usually does better. Don't bother with, Im feeling lucky.

It would help if you can post a link to a particular model of a RS3 or a photo of one you are interested in.
Some RS3's I have seen had a single horn but do not know what type of horn.
