@Danr posted:The manual for this locomotive is confusing since it states that it could be an LCRU OR Protosound. If you don’t have the box telling you what it is the next best option is to open it and post a picture as John m 43 suggested.
Thanks for that Catch Dan. I suspect that this is the model with Protosound because the Horn immediately blows when DC power is applied. PS1 engine startup in "Reset" mode and the horn won't function until you leave reset mode.
