Turnout and Crossover rail joints

Hi
I have been struggling for some time as to where to place the rail joints on turnouts and crossovers. Please see attached file. As an example I have used a GWR old style 12' 1:8 turnout and gauge of 18.83mm. I have placed the the peg on MXP, MVJP, TVP and TVJP using 4 separate templates. I understand these to be main road crossing point, main road rail joint, turnout crossing point and turnout rail joint respectively. Could you confirm that this correct? In the book from David Smith I see that the V leg distance from crossing intersection to rail joint should be 12'. I realise that the V length varied in crossovers but in my 1:8 crossover (not shown on the attached fie) there was a similar problem. When using the spacing ring the 12' circle did not match any of the pegs or the five marks (three on turnout and two on main road) on the track centre line. Its clear that there is a gap in my understanding. Should I just make the rail joints at the 12' point on turnouts or the appropriate lengths as per Table 9 of Smith for crossovers?

Best wishes
Graham

Hi
Moments after I sent the last post I came across a old post that mentioned the the real>v settings> custom settings>v rail. I think this will solve my problem. I will have a play around with it.

Hi Graham,

The peg positions are mostly concerned with the track geometry. The basic positions are:

For an explanation of most of them, see this old page:

https://85a.uk/templot/martweb/gs_geometry.htm

Scroll down to the table of PRE-SET PEG POSITIONS. Sorry it's so old.

To adjust the locations of the rail joints to match the prototype, some new functions were introduced recently in version 227:

cheers,

Martin.
