Decals not showing up in the exported model

[TrainGuy6550]

The .blend file, associated textures, ace files and .S file are attached.

-> I've made sure the faces are not intersecting with the body.
In Blender, the same issue happens. But it can be fixed by turning OFF "Backface Culling".
But I don't get how to fix it in the exported .S file. The decals do not show up both in the Shape Viewer (by Paul Gausden) and the TSRE5 Trainsim Fork Shape Viewer.

Why is this happening?

You need to reverse the decal faces in the model.

Thanks so much! It worked. For anyone else wondering, the fix is flipping the normals
