The reason I am interested in the PS-3 upgrade is that I have a number of the original protosound and non-protosound (whistle and horns) engines. Of these, there are a couple of the higher priced premier engines that I really like and the cost of a PS-3 upgrade would be a small percentage of the cost of the engine. I certainly would not waste the cost of an upgrade on an engine that only cost me a couple of hundred dollars to start with.
However, there are a couple of other reasons that I would like to upgrade to PS-3 and eventually have an all-PS-3 stable of engines. First off, I don't want to reply on a battery being charged determining whether I scramble the electronics board to the point where it must either be reprogrammed or, worse yet, it becomes unusable. I have worked in a hi-tech environment all my life and have loved it, but that doesn't mean that I want to have to worry whether my engines will go "off into the weeds" when I put them on the track after an extended period of time. This can happen with old protosound engines.
That brings me to my second point... Eventually all my trains are going to end up with the grandkids. The grandkids are not going to have the background (and version knowledge) to understand how these engines have to be treated to avoid possible catastrophic results when they drag them out years from now. I can see a lot of these engines not running when they first put power to them and a lot of them finding their way to the trash bin. Hopefully, with PS-3 and the absence of a battery, they will at least run. I guess the days of dragging an old 1950's era train set out of the closet and expecting it to run are gone with many of this generations engines... hopefully, PS-3 might alleviate some of the potential problems.
Oh well, enough rambling... When I start these "trains of thought", I usually have an idea in mind initially and then end up on a "side track" wondering what the heck I was going to write about. I hope I at least expressed some of my concerns.
I'd wait for the PS3 upgrade kits to be released. PS2 is a dying horse...let it die.
PS3 audio is just as good or better than Lionel Legacy Vision Line whatever. PS2 audio is like listening to the old 8 track player...PS3 is like listening to CD's
Folks on here are frowning upon PS3 as they can't do much component level repair..well so what?? First there has to be a problem to fix!
