I got some intersection designs that unfortunately uses bridges (paywalled behind a DLC) but thankfully the throughput is great according to my testing. I may or may not have made up the name Behlertrumpet.

Wow, that is one weird junction...

Designed a couple of new intersections. 4 spacing RHD, chunk aligned with power poles, buffered for up to 6 length trains in every direction. 3x3 chunks for the 4-way, 3x2 for the 3-way. Can get slightly higher TPM by signal spamming but I didn't care to double the signal count for ~5 more TPM. Quite proud of these, managed to exceed all my design goals and they look great as well. As of this posting I believe the Hourglass is the only 3x3 chunk intersection with room for proper chunk power poles and buffering - I searched extensively and couldn't find any others.

Hourglass 4-way: ~93 TPM

Tulip 3-way: ~76 TPM

Compared to the other junction I mentioned, these are much cleaner.

First train intersection design I've made myself (Romayne)

Score 176.74, settings shown in attached image.

2-lane buffered(?) 4-way intersection, elevated, RHD, 212x222

and

2-lane unbuffered 4-way intersection, elevated, RHD, 96x96

The buffers on the ends are kinda crappy but they help, there's a design attached without them too which gets considerably less TPM

Image

W/ Vestigal buffers


W/O vestigal buffers


Ohh my god did I make the same overall design as the person above me. LMAO. Not intentional :v

Decided to also make a 3-way!

4 spacing, RHD, almost but not quite a 3x3 chunk build, but made to be aligned for such. Has a few bits of buffering, and it seems to pay off!

Great! It's awesome that there are multiple spacing options. I added them. I didn't test all the varieties, though.

Great! I added them all, Though I added a name, it would be good if you gave me another.
The forum should now have all the designs updated, ping me if I missed a post.

I just double checked the blueprints for Spaghetti Junction and I accidentally left a small mistake in the variant with 4-4-4 tile spacing so here is a link with the corrected variant and I hope it will be updated with the small correction. Spaghetti Junction got misplaced with 2 lane intersections and a score of 98.88 indicates that the intersection also got mistakenly tested as a 2 lane intersection.
It would also be great if all the varieties of the intersections I shared (including the varieties of small turbo roundabout) got included with correct labeling of spacing and it also seems that Behlertrumpet is completely missing which probably is a mistake.
I'm sorry if I sounded a bit harsh but I still want to thank you for maintaining this topic.

Thanks! Just call me out if you find errors like that! I needed to adjust the script to include 3 way 4 lanes!
I fixed most of those issues, something with needing different names when grouping intersections.
What was the issue with the turbo intersections?

It's missing some extra variations that I included in a blueprint string found in this reply: viewtopic.php?p=640184#p640184

Hmm of course I forgot a name :P thought about it a bit and I think Messy Hourglass works, with the buffered ends being Messy Buffered Hourglass. Feels right to go off the name of the design so similar above it.

I'm glad to see more designs coming out, however, is there any thought to adding a new metric to these designs, such as the amount of ingredients used in these blueprints? When I look at the original post and look for designs, I want to be able to sort through that kind of data. I want a good score, but minimal supplies needed.

TBH what I want to see more of are intersections that take the possibility for elevated exits into account. Most of the current designs assume the entrances are always at ground level (which I know is partly necessary because the stations used for testing must be at ground level), but this is a flawed assumption with the new planets.

Of course this introduces a lot of possible permutations, but hey, more possibilities for designs.

I did add support for elevated exits:)

Made a rail book that fits between city blocks.
The trains per minute on the 3-way intersection is only 70-80 though.

I've never had enough trains to go even past 1 every few minutes (in my 1.1 save, I never used trains in 2.0) - let alone on the same junction.

Hey, I made my first non-crossing intersection the last couple of days. I ended up with this design kind of by starting with one element, and then fitting everything around that, trying to keep it reasonably small. I learnt a few things from the examples here and from the testbench, like the difference the number of signals can make to the scores, but also about buffering, which I hadn't been considering when making naive crossings.

Anyway, I really like the slimline cross and cube - I'd use slimline cross for my own game except I use 4 tile separation, and modifying slimline cross really messes with the amazing symmetry of the design. So I'll probably stick with my not-so-slimline design for now.

I'd call it the S-Junction because the elevated rails almost make an S shape.
