R104 Curve x8 (PF)

R104 curves have a radius of 104 studs, measured from the centerline of the track.  The outside diameter of a circle of R104 curves is 68" (1728mm).  A single track segment covers 11.25°.  

These tracks are all plastic, and work with any push- or battery-powered LEGO® train (namely Power Functions).  They are not compatible with the older 9V or 12V train motors.

Each set includes 8 track segments, enough for a 1/4 circle.

If these tracks don't meet your expectations, send them back for a full refund.  We'll even cover shipping.
