I would like to instal a sound on my aristocraft alco RS 3 but on soundtraxx product list there are to sound for RS 3. The horn is the difference? or there are two engine model on alco RS 3?
It’s just two different horns. All RS-3’s has the same diesel motor unless later modified by the owner railroad.

Without checking out the Soundtraxx website my guess would be one has the single chime “blat” airhorn that pretty much all first generation diesels came with, and the other is a later three- or five-chime air horn that would have been added by the railroad later.
A post on the NHRHTA forum discussed this recently. The FA had two of those engines. I have just bought two ABBA lashups of Proto FA and FB units. Is it feasable to put two sound units in each of them to duplicate that sound? Or should I put one in each of the four units?
Who said the FA’s had two diesel engines in each unit? They most definitely did not. EMD E-units (passenger diesels) had twin engines, but not the Alco FA’s.

I don’t think it would be feasible to put two sound units in an HO engine, even if the engines did have two. I run an A/B set of E units with only one having sound, and they seem fine.
Depending what RR you model and when you model it, it’s possible you could have a train where some of the Alco’s had been remotored with EMD motors, so that in say an A-B-B-A lashup of FA’s you could have a couple that sounded like EMD engines and a couple that still sounded like Alco’s.
OOPS! My mistake the FAs and PAs only had one engine the DL-109 had two. See the excerpt from that thread:
The locomotives I currently have are:
DL-109
FA1/FB1
PA1
I’m not sure what decoder I’ll be getting yet, but I’d like to find one that has the correct horn. The 539 engines that had turbo’s on them were the 1000 HP engines that were used in RS-1’s, DL-109’s, S-2’s among others. A DL-109 had two of these engines per unit so a two unit set had four of these engines.
I believe the horn sound should be a WABCO E-2 (sort of a “BLAAATTT” sound).
As for the motive power noise, the DL-109s used Alco 539s while the FAs and PAs used Alco 244s - two completely different sounds.
It looks like ESU’s LokSound has the 244 motor with the E-2 horn. I’ll start with that for the PA and FAs.

A well-recorded sound sample for one of the twin-engine units would actually have the right soundwith one decoder (or close, anyway). What about one of those Baldwin monsters, like 8 engines in it.
We’ve drifted far away from the original poster’s question here, he was asking about a G gauge RS-3 and the Soundtraxx Sierra sound, not Loksounds or Tsunamis or any of the rest of our midget scale decoders.

Oops !! I forgot Aristocraft is the big stuff. In that size, why not just put a real Alco engine in the locomotive?? [;)]
