These tunnels allow the marble to pass through the spacer instead of going around it.
Two different variants are included:
Straight Tunnel
The marble enters on one side and exits on the other side at the same height.Slope Tunnel
The marble enters the spacer and exits one level lower, allowing smooth level transitions inside your layout.
Like the other spacers in this collection, the parts are fully stackable and compatible with GraviTrax Junior elements.

This model belongs to my GraviTrax Junior Compatible Collection.
This is a fan-made accessory and not an official Ravensburger product.
