The radius of the circle that would be made by these pieces is 15 (any curved track you purchase should have a listed radius).22.5 degree variations mean that 4 of them make a 90 degree turn. 18 degree variations mean that 5 of them make a 90 degree turn. 15 degree variations mean that 6 of them make a 90 degree turn.Tunnel opening cross-section dimensions: 1.4 inches wide (1.1 inches at the very bottom) 1.9 inches tall.Train not included.

But don't go too deep, because the outer shell is only about 1 mm thick.
