Marklin 8520 - Z Track (195 mm) 7-11/16R, 45 degree Curve
Radius 195 mm / 7-11/16". 45°.
Charlie's Tips:
These pieces are 45 degrees each. That means that 4 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 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 8510
- For a wider circle, use 8530
If you would like a full box, order 10 pieces, they are packed in box of 10.
Track 8521 is the same radius curve. It is shorter, and only spans 30 degrees.
