Does anybody have any good overhead 4-way train intersections?

[Liwet]

I try to make one but there's no room for signaling or supports. So I move everything one tile out. Do the same thing. Still not enough room.

How wide does the smallest intersection have to be?

The dominant flaws inherent to the clover leaf design are two-fold.

Firstly, its required footprint is enormous compared to modern-day interchange designs that offer equal or better throughput. (Heck, there are even some contemporaneous designs that already performed better, iirc.)

Secondly, a weaving maneuver is needed at entering and exiting the interchange, creating two local bottle necks in either major direction of travel along the highway that limit the rate of traffic that is simultaneously able to cross the interchange by far more than it can hold internally. Which makes that giant footprint, a giant waste of unused space - for the most part.

Also- there's a relatively very short distance available to perform the weaving maneuvers within the interchange. This leads to high pressure on motorists to find their lane; leading to traffic hazards and incidents -- which actually have nothing to do with motorists' attention span; drunk driving; or anything of the sort. It's simply a flaw of the interchange design itself.



The iconic US clover leaf design, used first at Woodbridge, was actually a rip-off. It was copied off of a magazine cover featuring an aerial shot of an interchange in Buenos Aires, Argentina. Which basically was used as a base because it looked big and cool. Quintessential take for the US at the time, when bigger was deemed better.

Simple circle intersections can be plenty good enough ... unfortunately they don't fit into a single chunk anymore because the new rail curves don't go as tight, so my design is no longer viable.

[Chindraba]

Unless it's too tight, as has started happening lately, I'd much prefer to navigate a roundabout (traffic circle) than a cloverleaf. Having to slow down to 40 (25 mph) for a tight circle is just as bad as slowing to 50 (35mph) for a cloverleaf, but it still don't have the weaving as much as the cloverleaf does.

I've yet to make the flying junction I want to, but that's not relative here, anymore than cloverleafs are, since OP wants a junction all at one level, just not ground level.

@OP How many scrap trains are you running? Dedicated 2 way rails are likely enough to move scrap to one central recycling area at least until you can pave the oil oceans.

I've got a basic setup made which is giving me 2 science per second but I'm having problems with space and want to scale stuff up. So I don't know yet.

My plan is to use the largest island I've found to separate all the scrap into train stations that take each item to other islands that might need it. Sort of like a bot-based setup but with trains instead of bots; or maybe something like city blocks with islands. I anticipate lots of intersections, so I'm putting together some blueprints first before laying everything out.

[knighttemplar1960]

I drove around in a tank looking for 2 or 3 large islands close enough to connect with large power poles and roboports. 4 Scrap trains supply the basics at the top. 5 trains supply the quality island. The medium island is all accumulators and lightening collectors (in this screen shot they are all rare quality).

Surplus material from the basic supply isn't simply destroyed. Any thing that is surplus is moved by bot to the quality island where its recycled to create quality components.

All that said there just isn't enough traffic to even worry about intersections until you can pave oil oceans and make Fulgora a mega base and once you can pave over the oil oceans the elevated rail junctions required can be limited.

[Schobbob]

you could just use a dual-track system for all that

[knighttemplar1960]

Could but every thing I used was made for free on planet. There is no chance of conflicts, no delays for any of the trains. no signals required (which can't be placed on the elevated rails) and later can be modified to that when foundation is available. Once I have science pack production up to the point that I produce as many (or more) than I need per minute. All I need to export from Fulgora is holmium and things that can only be made on Fulgora like electromagnetic plants and recyclers.

I have been placing signals on elevated rails the whole time I have been using elevated rails. There are even screenshots on this very thread of signals on elevated rails.

I haven't been able to get signals on elevated rails. Attempting to place them by hand or ghost gives me a red signal that won't attach. Perhaps I should verify files.

Signal lights green would mean they are attached to rails and able to read them. Not a single grade-level rail so the elevated rails must be what the signals are attached to.

Has been done, can be done. Knowing why you've had no success is unknown.

I had 2 corrupt files. Working as it should now.

Indeed, plus my system is getting old. I'll need to replace it soon but win 11 has too many unresolved issues and my wife won't be able to figure out Linux.
