Somethink I ment  to ask was dose the newer track pices for instance the curve are they same as in the sizes / radius as they now called vintage curves.

Graham.

Scalextric Classic (old), and Scalextric Sport (modern) are generally the same size and shape for straights, half straights, quarter, and short, and for R1, R2, R3, & R4 corners, but they have different connections, so you need a converter piece to connect them together.

Thank you JasonB for information .
