I was able to replicate this bug using the instructions.

At first I could have sworn that it was working correctly, but then when I tried again, it did indeed incorrectly flip the BP as stated by OP.

avoiding base designs with chokepoints that need huge intersections?


I just tested the symmetrical cross 6 tile spaced LHD with 100x100 grids:
Score: 54
S1: 77
S2: 43
S3: 42
Note that one of the central blocks deadlocked.

We are measuring the throughput through each intersection. We are not measuring the throughput through a grid.

I've expanded the Symmetrical Cross to 8 tile spacing! Additionally, while I was doing that, it occurred to me that the 6 tile LHD could be 4 tiles smaller with slightly higher throughput!

Be aware that set 3 for 4 ways and set 2 for 3 ways have been modified. We will be retesting all intersections with these criteria. Set 3 of 4 ways and set 2 of 3 ways now include a 10% change to go a different direction as otherwise there was unrealistic behavior in the trains.

The classic: MultiCross. I wanted to parallelize it as a narrow companion to the hurricane and I finally did. The arms are less than 50 wide, which is my grid and I kept it to 250 x 250, so shorter in length than even the normal MultiCross.

I've also included 4 Tile versions! And convertible 3 ways ...

The design is compact when compared to other 3 way buffered design and still gets a decent score.

This is sexy! I haven't been considering no buffer on the front end. I should try some designs out!

I made a new high throughput 3 way. I call it demon mask. For some reason LHD scores lower and I wasn't able to equalize them.

Now also with a 12 length train version!

My only thing is that a lot of these latest intersections are huge . I don't think I would use them because of the extreme space they need.


Hmm, I feel quite the same way. That's why I'm trying to reduce their size. I figure that 150 is a lot better than 300, etc. And I've just made one that is ...

I couldn't get LHD to work because of the center grid. No matter what I did, the blueprint would have to be larger than 100x100 so I settled on just RHD.
