1 track tunnel - Curves radius 550
H0 scale reproduction (1:87) of an internal tunnel for single track railway lines.
Adapt it to lines with wide curves with a radius of 550 millimeters (radius R5) and must be combined with the corresponding portal for the same type of radius (initial code 1050.R550).
Each tunnel is 8 cm long and it is possible to extend it with other elements of the same type.
It makes no difference whether it curves left or right and is suitable for both lines with and without catenary.
It is equipped with a hole at the top to facilitate the insertion of a possible anchoring system for the overhead line.
3D printed with FDM technology in ecological dark gray PLA material, it is supplied to be painted.
