Today I picked up the the first package with kit of the Z6 and I have to say....

Wow! Excellent quality!!!!
I will not behold the pictures from the kits. Plastic bogies, RP25 axles, 3D printed parts, Symoba NEM Pockets, 3 frets for each wagon, comprehensive instructions, decals with 5 running numbers and easy folding (as I can judge from my experience). See for yourself:
- Buffers, NEM pockets, and 3D printed parts.
- Bogies and RP25 Axles
- Decals Sheet
- Comprehensive instructions with 3D expoded diagramms.
- Fret 1: Outer skin and reinforcements with roof. All folded together.
- Fret 2: Chassis and other details.
- Walkways, wagon ends, doors etc.
Enjoy
