Marklin 8530 - Z Track (220 mm) 8-11/16R, 45 degree Curve

Radius 220 mm / 8-11/16 inches. 45° Curve. Charlie's Tips: These pieces are 45 degrees each. That means that 4 pieces make a half circle. The radius is 220mm, which is close to 8-11/16 inches. That means that a half circle or full circle has a diameter of 17-3/8 inches. This is measured from the center of the track piece to the center of the track piece. The second picture shows the track geometry For a full circle you need 8 pieces For a half circle you need 4 pieces For a 90 degree turn (quarter circle) you need 2 pieces For a tighter circle, use 8520 For a very tight circle, use 8510 If you would like a full box, order 10 pieces, they are packed in box of 10. Track 8531 is the same radius curve. It is shorter, and only spans 30 degrees.
