    How to create an outside slip junction?

    Here is an example on Dresden-Riesa in Coswig:

    I can't figure it out.
    I tried making a normal crossing then placing the outside part.
    If I lay two crossed over tracks (without weld tool) and then place the outside part, it gives weird results. Like it's kind of recognizing it but not really. If I use the weld tool on it it works even worse.
    As far as I know you can't use the slip junction tool for it because it doesn't let you choose a radius.

    Does anyone know how to do it?

    EDIT: here is a screenshot of my attempt at making an outside slip junction.
    It recognizes some parts but some things are weird like rails going through each other without gaps.
    This also creates three (I think) proxies instead of one. Also the sleepers are weird. This is definitely not right.

    I found out that there are a lot more outside slip junctions in Riesa.
    Even double outside slip junctions.

    They even have curvature on all tracks

    And the weird thing is you can't use the slip tool on curved tracks

    So which tool is it then?

    I had only one case in the railyard of Limburg where there is a double slip junction.

    So, I tried to make the slip junction in the way you describe here (without the Weld tool, with the Laying Track tool) and it kind of work but just as you describe the result looked weird. The problem is if you use the normal track layering tool and you have a double slip junction, the radius (aka the curve) snaps differently on both slips and already this looks weird enough. Also it's a mess to get rid off the junction border signals (Grenzzeichen) if you create so many junctions at one place in this way.

    One thing I noticed which is important for a junction of any kind is that the tracks to be connected should be one the exact same height to not look weird (I recall Lukas saying that there is a way to create junctions on superelevated curves in the masterclass video, but it would be super difficult but this is also not our problem here now). Therefore one thing I frequently do is cutting the tracks around the junctions at the same distance to the middle of the junction and then bring all nodes to the exact same height. An even better practice is to have all the tracks on the railyard on the exact same height, with being all nodes having the same value, to avoid steeper gradients between these nodes and the rest of the track network.

    Unfortunately it is exactly the second junction to cross at the route, and if this one is going to look any weird, it would have an major impact, so that I ended up getting rid of the double slip junction and created just a simple crossover. Not the best way, but fortunately these slips do not have make much sense for my route, as they connect tracks which each other of an inferior shunting purpose.

    However, Using the weld tool correctly is really something they should have teached us to get singe and double slip junctions (and even curved ones) properly. And getting rid of slip junctions just because of this is definitely not a good solution.

    I think you're talking about a normal slip junction and not an outside slip junction (couldn't find an outside slip junction in Limburg, but I think I found the slip junction you mean).
    For normal slip junctions I just use the weld tool and for me it works really well. I have built several of them already.

    The thing about the heights... what I found out in order to make a junction on a gradient or a slip junction or whatever on a gradient, all nodes need be be kind of coplanar. That minimizes the weird-looking. You can see junctions on gradients and in superelevated curves all over the existing routes. It's actually not that hard especially once you get used to it.
    You know you can manually enter the gradient for each node after it has been placed already?
    If you enter the same value in each node of a set of junctions, you will have perfect junctions on a gradient.
    In fact on my route many railyards have multiple different gradients over them.
    This even works for slip junctions.

    And a quick tip for your Grenzzeichen problem: I don't know if it's to late for you (it's never too late but a lot of unnecessary work) but you can copy the Loft Descriptor Asset and past it into your own project and use it for the tracks. Then just remove the Grenzzeichen and/or the junction motor entry. So any new junctions you place won't have a Grenzzeichen. You can later add it back.

    But I really need outside slip junctions. There are a lot on my route (I think at least 10).
    And since I know that it can be done...

    And what I found out is that the whole slip junctions is a single proxy and even has special render component parameters so there must be something like a tool for it

    Ah, yes. You want an junction, where the slip curved is layed towards outside completely. That's differernt, you're right. The reason why I consfused it was that I just use the Laying of Track Curves tool and doing my slips this way, kind of has an equal effect to like as the yes it creates a real curve which connect the straight with the crossing track, not just a small slip. I didn't use the weld tool yet to be honest, but thanks to your tip I will maybe can redo a few junctions in Limburg now. Not quite sure how I can use it yet, but I need to see how I can get it to work out.

    Yes, I know I can enter the gradient for each node after is has been placed. However, how can one keep a gradient between those nodes if all of it have the same height (being coplanar to each other)? That's what I don't get at the moment. How can you keep this coplanarity between the nodes when these are one a slightly ramped up terrain for example?

    Oh, I didn't know this. Thank you very much. Until now I always had the hassle to delete them manually (even for the many times they are underneath or inside the track asset and I need to go under the surface to spot and delete them.

    Maybe it's up for DTG Lukas to answer this question. :)

    I would really recommend using the weld tool. If you're at one point doing a shunting scenario you would really miss the slip junction.
    Have you seen this post?

    Coplanar doesn't only mean they are the same height. It can also be on a ramp. As long as they are all on the same plane.
    You can achive this my making every node have the same gradient. So you can have a junction on a ramp. That's also coplanar.

    Yes, I bet Lukas knows the answer :)

    As a side note, maybe you should provide a screenshot of that, comparing it better to the result you want to have above?

    May I ask, did you made a writing mistake here or is the tool showing an incorrect warning? Because you wrote the opposite of the warning.

    Good idea. I'll do that when I'm home.

    Oh you're right. It doesn't work on curves. It works only on straight tracks. The screenshot is correct. I'll edit it once I'm home.

    You can make a diamond switch, if you look in the tool settings there should be a tick box to enable it when creating those type of junctions.

    Yes I also tried that but using this tool I can't make an outside slip. Only small slip switches.

    I don't know then, I've not played around with that much. I'll try to remember to post here if I figure it out.
