Larry-- I hear what you are saying!! Back in the day of all the command control systems being new, I want the layout to work on both DCS and Legacy. After messing with the Legacy for days, trying different things, I knew what the issue was, but no great ideas how to resolve it. I figured out that using tin foil did the trick but much like you, that really meant tearing a huge layout apart to try and fix it right. It also would work if you extended the antenna out of the engines to give them a better signal. I could run a 16-gauge wire, sticking it into the top of the antenna on a Lionel GP9, running it back on three gondolas behind the engine and it ran fine anywhere on the layout. But that was not practical as a fix to the issue. Maybe spending more hours would have led me to some of the fixes we have today but it was hard to keep spending time on the Legacy when the DCS worked fine.
I'm glad all that is behind us and there are parts now to make the Legacy system work on about anything and Lionel kept improving it.
My wife also thinks I'm nuts on more issues than trains!! The trains are actually a good financial hobby as if done right, you really lose very little money while enjoying something. My other hobbies are a blast furnace for money, so the wife may be right!!
