I guess you could call it moth interchange. I personally call it The Bean Interchange or The Peanut Interchange. No idea if there's real world prototype and name for it, created in an evening. A nightmare for manual steering.

When arriving from west/east
  • to go right, you go straight
  • to go straight, you turn right once
  • to go left, you turn right twice
When arriving from north/south
  • to go right, you turn right on the second turn
  • to go straight, you go straight
  • to go left, you turn right on the first turn
  • to turn 180, you turn right on the first turn and right again
But it looks fun and over-engineered, and the footprint is actually reasonable. It can also handle 180 turns, but only when going from north/south. Haven't extensively tested it yet unfortunately, but i have high hopes.

If 4 trains enter at the same time, each turning left, and they are immediately followed by 4 more trains, each turning left, the cloverleaf will fill up and jam with no train being able to proceed. The first four trains will be on the curved rails waiting to enter the straight rails on their way out of the intersection, while the second four trains will be on the straight rails waiting to enter the curved rails on their way into the intersection.

With the variety of intersections possible in 2.0, I think this thread is going to become unwieldy, especially with discussions and replies and new versions of intersections happening all in the same thread. I think it would be far more effective if people made new posts in this subforum for each new intersection, with discussion in that thread, then this thread was just for discussing the compendium itself, with the top post(s) edited with summary results and links to the other threads.

EDIT: Old blueprint had a bunch of weird asymmetry, made a much cleaner looking version. Also in RHD.

88x88, score 65.81, 10-rail spacing as shown, but can also be 6-rail spacing without making it bigger or slower.

Signals are a mess, but they're as good as I'm going to make them.

The final results of the first version were decent, but generally underwhelming.

This is the v2 version of The Bean interchange. It looks a bit less like a bean, has grown to take a bit more space, and lost the ability to handle 180. But at this low-low cost, it got quite substantial performance improvement over initial prototype on sets 2 and 3. This version is signified by a separate turning lane for crossing traffic from north/south direction, which also relaxes congestion for crossing and straight trains from west/east. It's also still a steering nightmare.

is it normal for my game to lock up when testing this? it doesn't explicitly crash, but it also doesn't look like anything is happening.

EDIT: i managed to get it to work. man it sucks. its only getting like 62 TPM. thats ass for a 4 lane train setup

heres the blueprint if anyone wants to test it. its a simple design, so the idea is its supposed to easy to expand by adding more elevated roundabouts. you can probably go up to 8 lanes before it needs to be modified.

Inspired by the cube, I made the half cube, as I like doing brick style city block designs. It has a throughput of 61.6 and looks pretty, as well as being a compact 84 by 50

While trying to build my own compact 4 way intersection, I stumbled upon two separate versions that are slightly faster. The fastest trades ease of driving for a little higher score.

I'm not 100% sure, but this can probably deadlock. At least I tried something similar and it deadlocked without chain signals.
If you get 3 (4?) trains from each direction that all need to make a 270° turn then each can enter the loop and get blocked from exiting by the trains from another direction.

Like any train system with a loop it will deadlock when the loop reaches the maximum number of trains it can hold and each needs to go further along the loop instead of exiting right there.
