Have never seen one before. Would be fun if Scalextric could start making more
"special" track pieces again.

They are a lovely part of the Scalextric back catalogue, Larsson, and I see you have a pair of adaptors ready to fit it into your circuit. It's a shame they didn't introduce the isolated rail with push button till they had changed to Plexytrack. I suppose it wouldn't be impossible to lay some copper tape either side of the "dead" slot to come up with a similar effect!
