I see references to this kind of track but don’t know what it is.
Marklin 3-rail HO track where the third rail is actually a series of studs which stick up from the tie strip.
The studs are commonly called “pukos”, for “Punkt-Kontakten”, meaning “point contacts”.
At this point we may have to admit that Bob knows everything!

Does Bob know why my car isn’t running right??? ;b
Of course: It is not a sufficiently-old Volvo.
There was an article in one of the mags. on different types of track a few years back. If I remember correctly the stud rail uses “studs” in the ties instead of a third rail and instead of a pick up roller on the engine/cars there is a “shoe/slide” that spans the spacing between two studs. I also think someone on one of the forums had brought up trying this consept.
The studs are probably like the domed head carpet tacks and are electrically connected under the track.
Here are a few pictures of two types of Marklin Stud contact track and the underside of a Marklin engine to show the slider pick up shoe. I hope this helps.
Thanks Bob! Although it is a fairly old VW diesel! ;b I think it got too much air in the lines after a filter change.
