The spiral from and to the shadow station takes shape.
Hans has started deploying tunnel overhead wiring because the height in the spiral is
insufficient for some locomotives as otherwise the pantograph would
get damaged.
for the overhead wire I use 2,5 mm2 installation wire because this
provides a sturdy construction.
The rail spiral is made out of half circles of 9mm multiplex,
supported by 6mm threaded end.
On the right side we will make the spiral to / from the shadow station.
Below you can see how we start from the shadow station to the spiral.
Areal view of the beginning of our spiral.
Inner turn will get a radius of 108cm and the outer turn of 120cm center to center.
