I purchased a Cruise Commander M as a last resort, along with an R2LC board and a C420 motherboard, and cobbled them together to make something that would give my MTH Blue Comet TMCC.

I got it to run both directions without an issue, but when I tried to splice in my serial data cable from my Railsounds Commander, I got sound but the motor will not move, even after I removed the sound system connection. 

Any ideas?

Thanks

Before you add that buffer circuit, try to get the R2LC and Cruise M to make the engine run again without Railsounds. You shouldn't need extra circuitry to make that happen. If you have any older TMCC engines you could try and swap boards to see which one isn't working. Also unplug your Command or Legacy base and see if it runs in conventional. Shouldn't need serial data for that.

I think for the 'M" you had to be at R2LC08 version at a min?

Yes, an R2LC07 plus a Cruise Commander M results in rocket speed as soon as the Cab-1 red dial is moved.  I had this happen once when upgrading an older loco.  Swapping in an R2LC08 resulted in smooth 100 step cruise.

Now that the engine will move, I was considering putting a dummy loco board in to power the sound system.

The one I have looks like the rcdr boards available from Lionel, but there are about twenty different rcdr boards listed, and several of them look like the dummy loco board. Any ideas which rcdr board is the correct one?

I wanted to resurrect this thread, because I just found out my CC-M installation ended in the train rocketing down the tracks.  I now know it’s because I have the R2LC07 board. 

What are my options?   Return my CC-M & exchange it for the R4LC equipped cruise commander?  Take my chances on a -08 board from eBay or new from ERR or Lionel?

Thanks for any input...

Tom
