Modern tmcc legacy engines in conventional mode. I’m having issues with my CW 80 not giving out a proper signal and screwing with my engines when I’m using them in conventional mode what transformers are recommended to strictly use modern engines like this

I recently acquired a older command controlled blue comet I don’t have a current layout I just have a test track set up with the CW 80 as soon as I apply power the engine will run forward lights will come on I hear sounds build it but it will not go into a neutral position or reverse I tried this with another engine that I know works and the same thing is happening . I don’t normally run my engines in conventional mode so I’m very unfamiliar on what I can use and what I shouldn’t use but the engines are acting as if they’re locked in forward position only

I would say possibly there’s a part failure but for two engines to work or act the same exact way I’m not sure. I flip the switch to run as opposed to program and I throttled up just a little bit so the signal would be sent from the engine to the transformer that it’s in conventional mode but as soon as it gets up enough juice it just goes forward . I’m going over to my buddies house who has a dedicate a Layout with an old ZW to see if there’s any difference . thank you everybody for chiming in and trying to help

Will keep everybody up-to-date

AFAIK, it's just the opposite. A CC engine is programmed to automatically start in conventional mode until and unless it sees a CC ("watchdog") signal. There is no specific signal to start in conventional. That's why one generally fires up the Legacy/TMCC base and put the remote on before turning on track power so the engine doesn't start in conventional if you're running it in CC.
