Has anyone a simple and sucessful method of removing the yellow design coloring from some of the "specialty" track pieces (i.e. power, crossovers, turns, etc.) without discoloring or damaging the track? (acetone??) They can be distracting and clash with scenery schemes. Thanks.

Nope...
I haven't been able to do that without ruining the track...
I would suggest painting over the marks...

Brake fluid worked for me.
