Generally, an engine will start more smoothly with CV2 at zero. If you're using 128 speed steps and set CV2 at 20, when you move the throttle to speed step 1 the engine it will jump from 0 to speed step 20. I usually only use CV2 if I have two engines I want to speed match, and one is a little more sluggish getting started.

You may find adjusting CV66 (Forward Trim) and CV 95 (Reverse Trim) up or down from the default 128 may make the engine run slower or faster.

Mattel still has the classics on the Thomas and friends classic channel and on Amazon prime . So don't worry lol back to the topic on future stuff

 what about large scale toad

@trainman203 - CV2 is the start voltage...determining the motor speed at step 1
I have never seen any factory or installed decoder with a default CV2 setting of 0
In fact...most mfgr's recommend anywhere from 2 to 26 for CV2 depending on the typical use of the loco
I already have CV3 and CV4 set where I want them tyvm

@jward - Yes they are DCC OnBoard units...I kinda suspected they may not be adjustable
They are not perfectly matched but very close

Dave, you're welcome.

All the HO models are Bachmann GP40's and SD40-2's...but I cannot seem to get anywhere using CV 2/5/6 to speed match

I have CV2 at 10 - CV5 at 255

The AccutrackII shows the same whether CV6 is 50 or 150

Am I missing something???

Are these the DCC OnBoard units that came with the factory decoders? If so they may not support CV5 or CV6. This makes speed matching impossible. If this is important to you, you'll need to replace the original decoder with an aftermarket one like the NCE Bach-DSL which is a drop in replacement. I am not sure why the original decoders do not support these very important CVs.

Cv 209 and 210 matter a lot with this.  Cv2 should always be 0.

You need to work momentum cv's 3 and 4 too.

Read the default settings on these and record so you can go back if you have to. 

This is a 4 way balancing act so be patient as you go, it will probably take a lot of trial and error.

Great to hear and thanks for the update! I will be looking forward to these.

Also, I'm looking forward to the N scale version of the Siemens Charger locomotives in the COASTER San Diego Commuter rail paint scheme and hope these are still planning to be released.

Yes, the two raised areas on the gauge are meant to go between the rails and they are a tight fit, as in you need to put one side  in and then exert a little sideways pressure to seat the other side. They are definitely not a drop-in fit; they are supposed to be snug. One thing you might try is to mount the gauge to different pieces of track - some are looser than others due to normal manufacturing tolerances. Hope this helps.

You were correct, got it to fit, thanks for the help.

Thanks for making me feel old today.
