Not the same issue from that symptom. If the engine boots up with sounds when the track is powered- then it is a symptom of not receiving the TMCC/Legacy radio signal from the base.
Typically if i's just this engine and other TMCC/Legacy engines run fine, then the engine's antenna- often the handrails might be shorted to frame thus preventing radio reception.
Again, the first thing a TMCC engine does when powered is listen for the TMCC radio signal. If it doesn't receive a valid signal from the base it times out and switches to conventional operation and that is when the sounds start on their own.
Yes, it immediately starts up with sound after powering the track. It doesn’t just sit quietly, waiting for command, like my other legacy engines do.
