Cheers, that has helped a lot. Is there a way to do half a slip junction just one side that has the track curve? In one part of my route (Bescot) has one and need to create on without the red rectangle popping up, or isn't that possible?

Yes, after the first weld creates the diamond, and the outline curves for the double slip appear, slide the mouse to left or right, and one outline disappears (then click to confirm). If the wrong one renders, undo, and slide the mouse to the other side. Voila, a single slip.

cheers, I'll give that a try if I can get the dam thing to work. I've done exactly what the video showed me but still the 2nd weld isn't appearing what am I doing wrong?

I am no route builder but I have played around with it, it will only offer the slip option if the radius of thew curve isn't tighter than the selected track rule allows I believe, so always try and select 'Yard' before doing tight junction work. I may of course be wrong though.

As you're just practising--or should be rather than trying to fit pointwork into a confined space-- start off with a really shallow angle between the crossing tracks, as Matthew says if the curves are too tight for the track rule in force you'll never get it to work. Keep practising and opening that angle up and you'll soon find the limit it'll deal with. It's a labour of love, but once you get in to the swing of things it does get easier.

how do you check the radius? I've been trying to get it to work this afternoon but still no joy in getting it to do it . Weirdly enough I did one by luck again though lol as a tester.
As I'm trying to line up my track up on google overlay it seems to be unsuccessful so is it worth not bothering and once its created move it and line it up with the map that way or what?
Cheers, Ian.

The curved part in double switches is laid according to minimum radius of the selected track type (more or less).
So if you want a bigger radius, try various types. Yard will have the smallest minimum radius and mainline the biggest. But it is all defined in the track rules, so no one can give a generic advice what to select.

Ok I'll have to keep trying until I succeed I have flicked through each track type but even that doesn't always work either, do certain track rules have more success than others? I am using WCML TV track rule.

Different track rules can have an effect on what your trying to achieve but it's mainly to do with crossover angle.
Also even if the angle of the crossover is correct make sure that ALL the tracks are straight, have never been able to make a single or doulble slip if one of the tracks has a bend, so I now assume that the software will not allow it not the geometry.
I do advise that you create a play area on a new scenery area, you can create and experiment as much as you like without any risk.

Ok then I'll do that fingers crossed it'll be a success.

I generally make them (if there is a chance) by laying two straights across each other, then make the double slip where they cross, then connect the ends to the rest of the network and delete the ends of the straights that point to nowhere.

Double slips can take up a surprising if tiny bit of extra length and if that is not available, the editor does not create them.

When you have straights at the double slip, check the ratio of their angle. That is: see how many metres you need to go away from the crossing for the distance between the outer rails to increase by 1 metre. Use the measuring tape for this.

A ratio of 1:8 is more for shunting moves, so your best bet is the yard track, because that tends to have the smallest minimum radius.

A ratio of 1:12 or 1:15 is more for high-speed movements and calls for a rather big curve radius in the connecting arc. So try mainline there.

Ratios outside the range of 1:8 to 1:12 (or 1:15 or so) cannot work. The exact limit is related to the definitions in the track rule file.

In the region of 1:9 to 1:10, you should succeed with most track rules.


If the above is too much maths for you, look at it this way:
Measure 10 m from where the rails meet (the left rail on the right track and the right rail on the left track). From that point, measure the distance between these two rails. If it is below 0.8, increase the angle. If it is above 1.2, decrease the angle at which the tracks meet.

Hi everyone I've mastered the slip junctions now, thanks for all the help and advice much appreciated.
