Ha...I didn't even know that these had sound...ha
I wish I could help you but I’ll say it’s a nice find! I’ve wanted one of these sets since I saw Taskforce2008’s Usui Pass video a while back.
I will be trying to repair the one I have of course but would love to ha e one of these sets complete with the box so if anyone sees one, let me know.
Is it me, or are some of those sound effects actually steam ones? Perhaps the one that sounds like a whistle is just meant to be the brakes (or axles). But then, why does it play while in motion?. Also, when it runs, the (simulated) engine sounds more like chuffs at a high speed. Only the "idle" sound is clearly that of an electric (or diesel) loco. Might just be the quality of the soundchip.
Ah, geeze.. I won another one. This one was basically the same price but came with the motorized engine and sound engine where the other only had the sound. Hoping I can run them somehow in tandem. The rear coupler on the sound engine is a magnetic coupler which has a switch to it so I may need to rig something up for it to work.
