Steam Repaint Help

[harryadkins]

I would like to reskin the 2-8-0 and 4-4-0 found here in the Rolling-Stock library. My problem is that there are so many textures in the folder. How do I determine which textures these locos use? I thought RW Tools would do that but have not been able to find that feature. My plan is to exchange the locomotive numbers for transparent files and put the roadname on the cab.
