I tested your coal/iron waggon. It crashed instantly when I set the train to use a line.
First thing I noticed is inconsistency of file names. Is it SGBW or SGWB. I made them all SGBW, according to the texture files, just to make the file structure a bit tidier.
Next I noticed that the count of matConfigs was wrong considering you’re loading 6 children.
In the schuetgutwaggon.mdl I changed from
matConfigs = {
{
0, 0, 0, 0, 0,
},
to
matConfigs = {
{
0, 0, 0, 0, 0, 0,
},
I had no issues with the XL truck station.
