Passing siding construction

[mrmtox]

Would like to put a single passing siding parallel to my main. Could someone with more experience/computer modeling tell me if my calculations are correct? Using EZ track - use #5 turnouts and add a 3" straight piece to each. Then add one 12" section of 33.25" R curve to each. This should give a straight line between the ends of the two 33.25 " R pieces that have a 2.75" center-to-center separation parallel to the main.  Correct?  Thanks!!

One error in my previous post. Should have said ". . .add one 12 degree section of . . ." NOT " add one 12 " (inch) section . . ."

Use 2.25" piece instead of 3" = about 2.8" between centerline

          2.25" -- 12 degree 33.25"
       / 
   #5 --- 9" straight

Thanks Hunt - when the pieces arrive I'll lay it out and see what works best for about 2.5"+ separation. Your opinion is quite welcomed!

Dear All,

Goofing around with AnyRail:

For the #5 turnout and the 12 degree 33.25"R curve, the two formulas are:

Center-line to center-line spacing = 2.36" + 0.21 x Divergent Fitter

Main line length to match siding length = 6.76" + 0.98 x Divergent Fitter. 

Using Hunt's 2.25" divergent fitter example above:

CL-CL = 2.36" + 0.21 x 2.25" = 2.83"

MLL = 6.76" + 0.98 x 2.25" = 8.97"


For the #5 turnout and the half - 22"R curve (11.25 degrees):

CL-CL = 2.11 + 0.21 x DF

MLL = 4.13 + 0.98 x DF

Kind of intuitive, but the formulas show that the 33.25"R curve system

takes more area than the 22"R curve system.

Hope this helps.

Sincerely,

Joe Satnik
