I initally gave this a negative rating but the author quickly responded and fixed all the flipped normal issues that kept the model from being usable at the time I purchased it, as well as some other problems. The revised Blender file opened in Blender 3.3.1 without any issues and looks very good and is nicely textured. Minor model issues: (1) Not real world scaled so I had to re-scale it and (2) some textures are not in powers of 2 so I had to re-size them. The completed model works well in Trainz 2022 and looks as it should. My thanks to the author for his quick response! Suggestion to author: Use real world scale for your models and ensure all textures are in standard powers of two (ie; 128x128, 128x256, 512x512, 1024x2048, etc).
