Is there a guide for how to create a custom template for a turnout where the crossing and blade types aren’t known?  Which end do you start?

Hi Richard,

The easiest way is to use the F5 mouse action until you have got something close to the desired size. The dimensions are shown on the info panel. And then adjust the various settings to suit the track plan or prototype. You might use the next switch size up or down, but it's unlikely that you would want one several sizes different.

Otherwise, you need to start off knowing at least something. For example you might know the desired turnout radius for a straight turnout. You can use this formula to get a ball-park approximate generic crossing angle:

 very approximate crossing angle = square root of (turnout radius divided by double the track gauge).

So for example in EM gauge (18.2mm), if you wanted a 2000mm turnout radius, a starting point for the design (for a straight turnout) would be:

 very approximate crossing angle = square root of 2000/36.4 = square root of 54.9 = 7.4

So you would start with a 1:7.5 generic-type V-crossing, see how it looks, and take it from there.

Or you might know the required length from the switch front rail joint to the nose of the V-crossing. Then you could use this formula:

  very approximate crossing angle = length to nose divided by double the track gauge.

If you post some information about the turnout you are looking for, it might be possible to make more specific suggestions.

cheers,
 
Martin.

If you could up load a plan of the turnout into Templot either to scale or adjust it in Templot to scale, then as Martin said

! overlay a turnout template on to the plan, perhaps starting at the switch end
2 Use the switch button to get the approximate size
2a If curved use curve button
3 Use the roam button to get the common crossings in alignment

After this seek help here for help with final adjustments

Good luck

Let's see Martin getting Templot to do a double slip in that. :D

I actually saw the railplane at Milngavie.  I remember being taken there by my father,  probably in the late 40s,  to see what was left standing.

I love the way it seamlessly and unobtrusively blends in with the landscape!  :D :D :D
