If using both this mod and Multiple Unit Train Control, it appears that the quality locomotives get replaced by this mod and not MUTC. From my understanding, the ideal situation would be that the combination of the mods would result in the locomotive first getting replaced by this mod, to leverage the quality scaling, and then further replaced by MUTC to tie the locomotives together.

But it appears that the 2nd replacement does not occur. I'm unsure which mod causes this, as from my understanding, MUTC should be compatible with any modded locomotive. The Quality locomotives from this mod should effectively just be a modded locomotive entity that just replaces the regular quality locomotive. So I think the replacement effect from MUTC is somehow getting cancelled or just not happening for some reason.

I made a post on the other mod's page, but have not seen a response so far. I figured I would also post here in case a resolution can be found.
