Turnout Radius's

What are the equivalent radius of the #4, #5 & #6 turnouts? Trying to layout some sidings and need to reverse the curve in order to get parallel.

Numbered turnouts do not have any equivalent radius. To get back to parallel, it is extremely simple to use flex track. You can also take the radius curve you desire and cut the track section at which point it is parallel.

you can cut any radius curve to fit. the angle of the frog is more important than the equivalent radius here. knowing the angle will allow you to trim any radius track to the proper arc. the approximate angles are as follows: #4- 15*, #5- 12*, #6- 10*........

note that these angles are not exact, if you try to use these arcs in track planning software like anyrail or scarm, they will not provide the parallel tracks. in real life, however, there should be enough wiggle in the track to make things work right.
