Over the years, I have owned probably over 70 Lionel TMCC or Legacy engines and have never lost the sounds in one. I have three Atlas engines with TMCC and all three of them have problems loosing sounds. The oldest is a Southern GP35 from their first run (with no cruise). I love the look and sound (when working) of this engine. When I run it, the sounds usually start out OK but 3 to 5 minutes of running and the sounds completely disappear. Once in a great while, they will return if I keep running but most often not.
The other two engines are the first issue of F3's in Southern livery. These units have TAS cruise. I have two powered A's and both have lost their sounds. Sometimes when running one will come on and less frequently, the other will also. It really sound great when both are working.
Why do you think the Atlas sound seem to have issues when the Lionel units do not?
