Varaction2 to test which loco is pulling the consist?

[AndersI]

I know how to do a 'wagon override', ie. the engine controls the livery of one or more wagon types, but how do I do it the other way around?

To me, it feels much more logical to have the varaction2 chain for a wagon test if the engine is X (or Y or Z...) and select a special livery from that, especially if there are more than one engine type involved. But I can't find anything for it in the Wiki.

Am I blind? Stupid? Or is the answer only that "it isn't done that way"?

You can check variable C6 for the vehicle ID you want. You have to use varaction type 82 to get the info from the "related object" which is the loco.

Thanks! So, it was blindness - how could I miss that one? Seems to work exactly as I want (Yes, there's a very low percent chance that the Green Cargo trains have other containers loaded too):

Great looking sprites. I also like what you're planning here with Green Cargo. Very cool idea.
