Could you tell me the minimum layout width I would need for the following curve radius:
22 radius -
26 radius -
28 radius -
To the edge of the layout -
22 = 46"
26 = 54"
28 = 58"
You would want a little extra so the track is not right on the edge.
FYI -- Roadbed of HO gauge E-Z Track is just a little less than 2 inches wide. Radius is measured to centerline of track.
