I posted a similar question on the JMRI User’s group but I cant get a straight answer OR I can’t understand the answers.
I have a locomotive BLI Paragon 3 SD7 that runs too fast at speed step-1.
When I read the decoder V-Start is at 0 and if I choose Speed tables (and the correct CV29 setting) the #1 sLinder is all the way down.
Is there a way to get this loco to run slower at speed step 1? OR do I need to use it as my default loco and raise the other locomotives?
Gary
set cv3 and cv4 to zero. These are acceleration. BLI has PDF manuals on their website. Make sure you are on the maximum speed steps. Lowering Vmax and Vmid will also change the step voltage size.

Ok so don’t use the speed table. Use Vmin-mid & max. CV 3 & 4 = 0 and try lowering V-Mid and Max.
Thanks.
If V-Start is already 0 and no speed tables are set - that's as slow as it goes.
You want locos to go slower - hit the 28/128 button and switch to 128 speed steps - EVERY loco they review in MR, when tested on 28, ALWAYS starts slower on 128. Minor annoyance with NCE, it always defaults to 28.

If V-start equals zero, I would think that the engine would not move at all.
Nope. I've had a few decoders that just wouldn't go slow enough - even when CV2 was set to zero. Thats why I've standardized on TCS and ESU for my decoders - especially with my switchers. It's worth the extra few bucks for the great motor control.

Time...It marches on...without ever turning around to see if anyone is even keeping in step.
I have an Atlas with the dual mode decoder, and I had the same problem, it started fast enough, that I couldn't even do slow switching operations.
The Atlas help desk said to try a reset, I did, and all is good.

V-Start is generally additive. 0 seldom means no power, it means no extra. There are a few that if you set it to 0 always make it 1.
thanks Randy.
I guess these two locomotives won’t be in a consist together. I can get the mid and high speeds matched but not the start (step 1 - 5).
I'm surprised your BLI Paragon doesn't run slower.
Before you give up, have you tried resetting the decoder and then testing the start speed?

I'm saying - try 128 speed steps, guarantee it will run slower on step 1.
Definitely do a reset, in case something else got messed up, but 128 seems to always do better than 28, sort of makes sense, the speed range from 0-max is the same, if broken into 128 (it's actually a few less) means each increment is that much smaller than if the same range is broken into 28 steps.
There's nothing to change in the loco - 28/128 setting is the same on the decoder, it's what the command station sends that determisn which is used.
