In a tutorial on how to build crossings, the teacher used a "GX_crossingpanel 01". I cannot find it in my assets lists (I had it before my computer crashed). Panel 02 is there, but not 01.
Since I restored my computer everything in the asset lists is out of order anyway. Making things hard to find.
First, does anyone know how to get the asset lists back in order? And, two, how can I obtain "GX_crossingpanel 01?
Thanks for any help you can give me.

Its in G-Trax routes if i recall. I only have the Kuju version and the RCAP version.

oddly I have run into the same issue and can't find the file that this was zipped in, have you found it yet?
