So I have a DDA40X (62105) from bachmann and I would like to get sound on it but I also like to run a DD35B from my club's set. I could get a peronsal DD35B and put in a sound decoder (SDXH166D) and speed match it, or should I just replace the decoder in the DDA40X and use the other decoder in the DD35B (or run a dummy)?
I'm a bit confused. What decoder is currently in your DDA40X and what decoder is in your club's DD35B? Are you thinking about putting the SDXH166D decoder in the A unit and moving the existing decoder to the DD35B that you haven't yet bought?
If it was me, I would want the sound decoder in the A unit just in case I ever wanted to run it alone. I would also suggest you get decoders from the same manufacturer for both units. I've had difficult in the past speed matching decoders from different manuafacturers.

I ended up getting a non-sound LokPilot V to match to LokSound V and they speed matched perfectly. The CV settings are the same for both except of course for those related to sound.

The club's DD35B is a dummy and it is a dh126

Yes, I also was thinking about leaving the dh126 in the DDA40X but it looks different inside from a standard one (thats what the member I bought it from told me at least). i will need to crack it open soon to inspect it but for right now the electric motor sounds are annoying
Since both are Digitrax, they should speed match well. As I said earlier, I would want the sound decoder in the A unit in case I wanted to run that stand alone. Swapping them should be easy. I think both decoders are 9 pin plug-ins so just unplug the DH126 from your A unit and unplug the SDHX166D from the harness it comes with and plug that into your A unit's harness. You'll have to wire the other harness to your B unit and then plug the DH126 to that. If you don't want to bother swapping the plugs, it just means you'll have to solder the harnesses to both locos.
Ok, thanks for the preference.
