Tallinu I used the black signal to check for deadlock, and to see where a filled lane would end up in the senter. I thought that the names would carry over:/ Yeah you could probably remove half or 2/3 of the signals and get the same throughput BTW I am pretty sure the multicross would get a higher ...

Hans, I pasted in that blueprint about five minutes ago, and as I edit this note in, Factorio is still frozen. But I could see just from waving the blueprint around that you have way, way too many signals on your straight lengths of track. How many thousands of unnecessary blocks is that? :lol: -- O...

I found that I had to double the length of the split tracks leading to the paired train deletion stops, otherwise the exit tracks were backing up and throttling the max throughput of the junction. Any train more than a car or two longer than the defaults might experience a similar issue, and a trai...

Yep, I was wondering if something like that might be the case too... :lol: On a related note, I've been messing around with a long train version of the MultiCross, currently scaled for 14 car trains. To avoid making it incredibly unwieldy in length it has two of the less important buffer strips remo...

Aaargha, On one of Xterminator's recent videos, I found a blueprint book of four 4-way junction designs by Captain Crumpet, and ran some tests on them. They come signaled for LHD. You can see them all well enough in the video so I'm not going to bother making my own screenshots of them, you'd probab...

To what extent can I just take one of the existing highly-ranked 4-way intersections and delete parts of it to get a good 3-way intersection? Does the throughput generally carry over? Well, doing such a conversion optimally is not quite as simple as deleting the extra entrance/exit. For best perfor...

Are we getting something to make the bots stay in the green zone? "Optimisation of logistic robot movement" should include making them a little smarter about where they try to move and when. While "staying in the green zone" would be a nice to have feature, there are tons of oth...

The improved version lets 7,7 trains per lane/min pass. With a max throughput of 342 trains/min. But since the input is 346 the buffers will fill up and it won't get 6 trains ready in every lane before the next green light and the throughput will be lower. If it let's 7 trains pass through every gr...

Really nice done with those combinators! I wanted to make a controllsenter, but had not gotten to that yet. The deadlock situation can be fixed, you just have to check every output lane and block the input lane if the output lane is full. I am working on improving it to get 346 trains/min. I'll try...

You're right, a real use-case situation where any exiting traffic might possibly get blocked would absolutely trigger huge deadlocks. I managed to make that happen accidentally even, just by adding more signals on the left turn tracks to smooth them out while fiddling with the combinators right as a...

A high throughput 8 way intersection It works like a 8 way road intersection, and i have no chain signals in the senter. I don't know what you mean by an "8 way" road intersection... The contents of your blueprint string is a 4-way intersection (as are all versions of the MultiCross, and ...

That works really well: Thanks! Nice recording, shows behavior for both light and heavy traffic. hi, is there a version of this post for 3-way intersection throughput also? I have a save where I added a very basic 3-way test profile (east, west, and south stations are used), as well as a lane chang...

Windmill Mk2 modified with Merge-O-Matic exit lane optimizer, pushing two-lane performance to 93-94 TPM: 0eNrtnU1uXEmSrbfS4LAhFq7/uyeqalTD7H7DN2gUBKYUqSSeRAoUldWJghbQu+hBr6xX8iJIBhmMcLv3fC4pRaZiUoWUyCO/bj9ubmZu558nP739uHp/dX5xffLDP0/OX11efDj54T/+efLh/M3F2dvNn13/9n518sPJ+fXq3cmLk4uzd5v/ujo7f3vy6cXJ+c...

Tested without U-turns and I borrowed the lane changer Tallinu posted to deal with the specialized rails. Cool. :D I'd guess the one Tallinu posted on the last page is probably pretty close to optimal, though you'd have to scale it down for a 2lane design. Alternatively you could look at the "...

That is going to make it so much easier to change or create new templates. Also, I've just noticed something interesting and useful about the way signals work when placed on both sides of a track, which could be used to simplify your counters, completely avoiding the need to send an R signal to swit...

I've added a few of the intersections posted and one I was working on before going away which turned out to be not too far behind Windmill MK2 but more compact. Complete list: Inscribed square (aaargha), Windmill MK2 (Tallinu), Double squareabout (19wolf, Tallinu), 4-lane Multi-cross (Tallinu) Stil...

I used 32 spawner and some circuit logic to make them interweave in an exactly timed pattern so they accelerate all the way while pairwise merging till there is a single track left. Maybe with longer acceleration one could pack the trains more dense but my setup already was HUGE. With 1:2, 2:2, 2:3...

The "snap to station" feature when building locomotives that was added pretty recently also makes this much less of a problem as you don't need to drive the trains around any more. Unfortunately I'm not sure that actually helps. I know it doesn't if you're modifying an existing template t...

Aaargha, good to see you back (and to know you were just on vacation)! :D It fits in 4 chunks. Wondering how well it works.. I gave this a test run, and it only got about 30 TPM for set 1 and 40 for set 2, even after I replaced eight unnecessary chain signals around the outside with regular signals ...

Alright, here it is. Four lane T junction sized for six car trains, getting around 112-116 TPM. Since there are only three entrances and exits this is approximately equivalent to a four-way junction that scores around 150 TPM. I was surprised to find that it was noticeably slower than the fastest ve...
