what is pertihak please ?

"Pertinax" is a copper coated material that's used for circuit boards. It's what I had laying around. Very sturdy stuff. But some 1-1,5 mm styrene will do the job as well, I'm sure.

Sounds like what is more commonly known as Paxolin in the UK, sometimes used by railway modellers for sleepers under handmade track.

At a guess, Pertinax is a German trade name for something that is much the same thing.

It's probably the same but it will work as well with a slab of 1mm styrene.

In the meantime I've fitted the junction signal with a maintenance platform.

It's scratch-built, mostly from cardboard... ::)

Here's some pictures of a ground signal I built today. It's a dummy, of course.

For the mast I used a length of 1.2 mm brass tube. A 0.8 mm red LED is glued to the mast with a drop of superglue



The signal disc is made from cardboard. I poked a very small hole in the disc where the red lens should be



The counterweight is just a thin wire and a round scrap piece from a laser-cut platform canopy strut which has about the right proportions



Voilą. There's not much to it and took just about two hours to make.
