I’ll try to find a piece of track to measure when I get home, if nobody else answers first.
For what it’s worth, one of the main reasons I changed from Scalextric Sport to Policar track was that the metal-lined slot was too narrow on the Scalextric track. It gets even narrower as the track gets old and begins to distort, to the point where it will sometimes ‘grab’ a car guide as it goes over a track joint. The connection between track rails isn’t very good, either. It relies on tabs formed from the ends of the rails just pushing together.
