44852 IS 12.5"R X 30 degrees.
#4 and #6 refer to the angle of the frog where the rails cross. There is no radius on these switches because of the compound curve.
If you are planning a railroad, you'll find the degrees of the curve to be much more useful than the actual length of the track. But if you actually have to know, length can be found by this formula:
radius x 2 x 3.14 divided by (360 / number of degrees)
Approximate angles for the #4 and #6 are 15 degrees and 10 degrees respectively.
Thank you for your answer. That is if you know the degrees... I am only surprised that there is no catalog like that, made by Bachmann... I used to have, long time ago, a train in TT scale (it is true, made by Germans!!). It was much simpler, a turnout for example was like 2 tracks half-size, one straight and one curved, on top of each other. And they had only 5-6 dimensions (lengths) for all tracks (divided by 2 from the previous), only one radius. Much easier to play with... And for this, of course, there was no need for a catalog. But now, considering the complexity and variety of tracks, I am surprised that such a catalog doesn't exist. I don't think that Bachmann doesn't have the specifications I asked for! So they will need only to post them on-line or print them.
