Rrgh..... botlight is the bottom light. Without downloading the .rar file and opening it (I'm on my tablet right now and don't have any of my Trainz stuff), aren't there a couple of different .im files in there? IIRC, there are 3-4 different meshes in there, some with the bottom light, some without.
a) use another mesh (rename it body.im)
b) Find one of the Jointed Rail freeware locos that has the bottom light on it and copy it out of there.
Did you mean to keep it white around the headlight or were you not able to find it on the map? I'm pretty sure it is on the second map (map b?)
I'll give that a try Scott. Actually, I just did a quick mock up to see how it would look. I get the details a little later.
Edit: I got it good with the GN F7. No errors. I'll try to get some more work done tonight. This is getting exciting!!!
