What is the white and orange icon for and why does it turn green
if I move my mouse over it. I cloned the Test track and added a
few engines and tanks cars to it. Ever thing runs like it should but
I have one small problem.

or how I did it or even how to fix it. When I open the route up
I have a close up of one of the bottom of one of my engines.
This is in both the editor and in the sim. I can use the arrow
keys to get a normal few. Is there an easy fix. If I re clone
the route please tell me what not to do so I do not make the same
mistake.
