I like to tinker, and I have a nice looking and running Lionel rs-3 I got from Craigslist for less than $25. I don't know the model number, it's an older one from a set with a single motor, electronic e-unit, and basic horn with the speaker in the cab. I was thinking of adding a second powered truck, and maybe sound...
I can probably get a powered truck from the bay for cheap, and wire it in series with the other motor, but will the e-unit be up to the job?
What options do I have for sound? I'm used to HO where there are sound decoders from several manufacturers for pretty much every Diesel engine ever made, but what about in O?
I'm pretty sure I'll add the second motor as long as the e-unit can handle it, but the sound might be another story depending on cost...
