Smoke Density on Pennsy GP-7's

[miata54]

If this has been mentioned before, please disregard. If not, hopefully it will be addressed in future updates. If it is merely a "settings" issue", please let me know.

Selected "Horsecurve in Summer" and started out with the 2 GP-7's pulling a mixed consist. Three GP-7's were bring up the rear. All but the leading loco showed heavy smoke particle density at idle. At 13%, the lead engine matched the helpers. Toggled back to 0% and the lead engine's smoke reduced in particle density as it should, but all the helper engines remained at heavy dark particle density.

Do others see this same effect or is it just me?

Thx

Yes, the dynamic smoke on the GP7's has been broken since it was released.

Looking at the engine.bin's of the GP7's and comparing it to the F7's, it looks like its not using the new 'tractive effort' based smoke system. Its still using the 'active' system of before.

Smoke *should* be RPM dependent - or a little more accurately Tractive effort * speed which works out more or less constant for a given RPM ( as it should, it's Power ). The load on the engine doesn't go down as it gets faster, but the tractive effort the whole thing lays down certainly does, which is why hooking it up to the tractive effort reading makes the whole thing look rather silly. If you want it really accurate you have to account for field excitation in the generator but a) you'd have to be nuts to do that in RW and b) probably not noticeable.

I don't think that's got anything to do with the rear engine smoke though. I have to modify that basic script I had around that Mr Cowen installed, so I'll see if something changed with emitters.
