pat, I 100% agree with you. its a shame that an over $700 dollar steam engine has a software issue,but it is what it is.
I will probably just keep it as it is. the train link feature is nice and you keep from toggling with the engine button from car to loco so much. ( guess you do that anyway with the train link) although I find that button easier.
so for no more than I will be running vision sound cars with this engine( not like its all the time that is). it is not worth sending back.
I am just glad to know what the cause is. I just learned somthing again. thanks guys.
