Marklin 8521 - Z Track (195 mm) 7-11/16R, 30 degree Curve
Radius 195 mm / 7-11/16". 30° Curve.
Charlie's Tips: These pieces are 30 degrees each. That means that 6 pieces make a half circle.
The radius is 195mm, which is close to 7-11/16 inches. That means that a half or full circle has a diameter of 15-3/8 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 12 pieces
- For a half circle you need 6 pieces
- For a 90 degree turn (quarter circle) you need 3 pieces
- For a tighter circle, use 8510
- For a wider circle, use 8530 or 8531
If you would like a full box, order 10 pieces, they are packed in box of 10.
Track 8520 is the same radius curve. It is longer, and spans 45 degrees.
