Format:

Blender 2.79 / Cycles

Materials:

Principled Shaders

Scale:

1:1 (real world scale

Scene:

The scene utilities:

Layer 1 (Geometry and render model)

Layer 2 (track parts and train in "un-posed" stance"

Layer 9 & 10 (cameras and lights

Linking:

The model train uses hierarchical, linked bones for posing and positioning.

Maps:

1xHDRI

1XJPG (diffuse)

Geometry:

The modifiers stacks are left intact. A dummy controls each bent track part with regards to angle.

This prevents missing map links and pink materials

I truly hope you enjoy the scene!
