2.0 Intersection Compendium

This post was made because I had a working 2.0 intersection tester. as the main test thread has updated theirs, please go and use that one

You can test these designs: viewtopic.php?f=194&t=115929

There are 2x 3-way and 2x 4-way junctions inside.

Idealy people can test these themseves, but given the less than perfect tester (an hour and 20min was not enough time to port the mod), ill do these for you
LuziferSenpai:
3way flyover: a respectable score of 58
3way half cloverfeild: a less impressive but still reasonable score of 45
4way advanced roundabout: deadlocks as the roundabout does not use chain signals
4way : a very nice score of 79, however '4way' is to generic a name for the list, what would you like it to be called? i see its based of a turbine interchange

DaveMcW:
Cube: really showing the KISS design principles, and it works, with scores of 90.7/90.9 for RHD/LHD respectivly

I will add all the successful intersections to the main post shortly
and these tests made me realize that the tester needs better handedness detection for chunk aligned intersections and those with very narrow track spacing (which will be more of a thing in 2.0)

to add one of my own designs to the list I present the streamline flyover 3-way
Image

its rather wide as a whole, but narrow in profile. I could make it smaller but that would involve making it manual driving un-friendly, or changing the rail spacing.
it gets a score of 83.6 which is around the same as the best 2lane 3 way buffered intersection from 1.1
i suspect the 2lane 3way limit for score is around 90, with the 2lane 4way limit around 115-120

Bocian2 has published some of his ideas for elevated rail interchanges in this Reddit post.
I created blueprints for some of his Celtic Knot designs.

Variant A is near identical to the design from LuziferSenpai, but Variant B is both different and pretty good with a score of 89 for RHD and 86 for LHD


as an added note: i went and tried to make the intersection from FFF417
Image
Im not 100% sure on the north and south outputs as we cant see them so this is just what i got to work
as the largest intersection tested and the first 4 lane design, it unsurprisingly did rather well. what i was not expecting was a score of 209

EDIT: Added stats.

Here's a 76x64 tile 2-rail-space intersection, very directly based on boskid's best-in-class submission to our communal competitive efforts on Discord about a year ago.

With no buffers inside:

Here is a 3-way intersection which is compact (72x40) but requires 5 ramps. It's like half of the 4-way Cube intersection with some space optimizations.

Some sort of merge between Star intersection from OpenTTD and whirpool intersection I used before. Call it whatever you want.

I have added ruspartisan's design as they had a test results screenshot

can other people also use the actual tester

I will eventually go though all the designs submitted, but priority will be given to those that have already been shown to work in the tester

I'll try to submit some bug reports soon to get the tester working with more intersections.

Simple intersection. Fits into a chunk (but needs buffers after the intersection). Should be fine for non-megabase stages of the game. At last we can make this one, previously impossible because signals could not be placed where needed/

I'm not 100% sure, but this can probably deadlock. At least I tried something similar and it deadlocked without chain signals.

may depend on train size, i haven't tested train that are longer than the junction, i don't see how it could though, if you have room for train outside the junctions they would always clear it seem to me.
