Choosing sectional curves

Set a radius around the equipment you run

Measure the room on your board and check the minimum curve of your longest or most restrictive equipment. Include room for the track base and the overhang of cars along the outside of the bend.

Use angle to position the next joint

Two pieces can have the same radius but different angles. Use the angle per section to work out where the route returns to a straight or meets the next branch. Keep the intended centerline visible as you test-fit.

Compare these selections

Department questions

Is radius the same as overall width?

Radius is the distance from the curve center to the track centerline. Use twice that distance for the diameter, then allow for clearance.

Will all pieces at the same radius turn through the same angle?

Check the angle on the exact product. A shorter arc can share the same radius as a longer curve.

What does half curve describe?

In a sectional family it commonly describes a shorter arc. Read the manufacturer’s angle for the selected part.
