The trouble is that I don't own any Scalextric track nor have I ever seen it in person!

What are the A and B measurements?

Do the metal rails actually form the outside of the slot?

I also heard the slot wide is 1/8 inch. Is that true?

Thank you all for the help with silly questions!

the metal forms the slot, but only for Scalextric track. Other brands add a plastic liner to the slot, making the rails wider than on Scalextric track.
A 1/8" slot is a good size.

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.

I've been alerted that HO cars can run on Carrera track. So I should get the measurements from that as well. I'll make a specific post for that inquiry.

11mm with a 2.5mm slot. For Scalextric sport.
