Curves and Radi
« on: May 23, 2011, 04:55:26 pm »
Hi all,

As I am new to all of this railway modeling and the forum can some please help me with planning some basic curves. I have worked out that ST-12 = 9ins curve, I am not using Set Track for the layout it is for help only in getting the curves right using SL 302.

What I am looking for is an inner curve of 12ins and outer curve of ?? :-\ with the streamline spacing between the tracks. What would this equate to in Set track if anything?. or would it be better to work it out on a track cad program,if so any suggestions?.

Sorry to go on a bit but have problems in relating my thoughts into words, this is down to my disability (Nothing works in a hurry anymore)  :thumbsup:

If you keep to standard track spacings then you will not go far wrong. On straight sections the distance from track centre to track centre should be 22.9mm and this increases to 24,7mm on curves. For convenience call it 23mm and 25mm. No one will notice 0.1mm anyway.

Thanks for the info it is easy to understand, have looked a books on it and got all confused but using those measerments makes life easy.
I always try things the complex way first instead of asking for help but now I've found this great forum my hobby is coming to life.
