Modern ICE Model Railway Tunnel Portal TT N HO

Modern Tunnel Portal for Model Railways (inspired by ICE tunnels)

This tunnel portal is inspired by modern ICE routes in Germany and adopts the clear, simple lines of current tunnel architecture.
The model is intentionally not yet entirely perfect – but it is completely sufficient for its first use on a model railway. Anyone who wishes can seamlessly integrate it into the landscape with plaster, filler, or paint, thus making the typical character of modern new tunnels even more realistic.

💡 Suggestions for Improvement & Further Development:

• Finer structures and textures (e.g., concrete joints, emergency exit markings)
• Variants for single- and double-track portals
• Adaptations for different gauges
• Additions like tunnel lighting, overhead line outlets, or side protection walls

I would be very happy if someone takes on the idea, tries out their own adaptations and shares the results here – this way, we can develop the model step by step and improve it together.
