Tunnel inner wall for the tunnel entrances

When looking into a tunnel on most model railway layouts, you look into a black hole. The layout becomes much more realistic with interior tunnel walls. The tunnels can be 
lined with either a stone or a rock structure. Each pack contains a left and a right straight or curved interior tunnel wall.The wall structure corresponds to the Hard foam series Stone Wall PROFI-plus

NOCH PROFI structural hard foam is the perfect material - and there are many good reasons for this: The tunnel interior walls are very light, yet stable; they are extremely realistic and can be easily reworked with a cutter knife and cut to size.

Note: The curved "tunnel inner wall" is suitable for everything in the PROFI plus rigid foam stone wall series.
