Trainman2 posted:Unlike Lionel Legacy, even if only one loco is selected, the features program on all you other engines. I discovered this when my K4 made the wrong sounds. You can change the decoder frequency, but I haven't tried that yet.
Never heard about changing the frequency, that's not how DCC works. As for programming more then one locomotive, that depends on how you do it. If you are programming on the main and have more then locomotive with the same DCC ID, you could be programming more then one. Also, some command systems program per the selected locomotive, or program all, depending on how you enter the program mode. This is in case you have several locomotives you need to program the same way all at once. If you use a programming track you won't have this issue.
