Strange Lash-up behavior in DCS

do a track signal test with each, then do another test with both on the rails.

What's your power supply?

You are saying the converted F-3's are starting up on their own when you run the 44 tonners and vice versa.

With both sets of locomotives on the track the second F-3 isn't getting the DCS command instruction signal then? 

Just curious, all have different engine numbers right? What type of track? All outer rails common? 

As Joe said, signal strength test?

Upon further investigation, I found that one of the 44 Tonners and one of the F3’s had the same address.

I deleted all four engines, reloaded them on the remote and recreated the lashups.

Now the newly created lashup work properly.

I have no idea how I ended up with two engines with the same address.

Thanks for your time.

Glad to hear you have it resolved, been to other layouts where they have that same issue. Seemed multiple remotes might be a cause as engines are in three remotes, each with a different address, and then are deleted and re-added at a new address in the remote when engine is not found.
