Off the cuff.. Your 8 reactors should handle over 100 exchangers so that looks good. As a quick test I might recommend putting a pump at the end of each line of exchangers just before your underground pipe. If it's an issue of clogged steam pipe that should help. If it does help then you need to div...

Some smart beltwork but I think this will break if you switch from say a 4 science pack research to a 3 because it stops loading the 4th leaving it to fill up belt space so you need some kind of loop. The other issue will be of pack creation. If you run into a deficit of one pack it will mess up you...

OpenTTD was really why I settled on "when stopped" (and at waypoints) in order to avoid using too much CPU time.

You seem to be missing 61 items for construction. Perhaps Requester Chest is one of those items?

Troll is troll

Purpose Increase throughput at large depots and remove the need for "creative solutions" to trains ignoring empty bays. Problem Currently trains chose a desired path and refuse to change this path for long periods of time. The effect is that a train may sit and occupy a waiting bay while a...

A properly signaled station with multiple stops will work without the circuit logic. Trains automatically go to an empty station with the same name if one is occupied. This is not true in any useful sense. A train will wait a very long time for a path it predetermined and ignore open lanes until so...

The real bug here is that 4 inserters fit in that gap and all 4 reach.

Why do we need this again? Also, I dont know where you got that 4to4 from but it wasn't the wiki.

It looks like too many power connections already. That middle pole looks like its connected to the pole above, below, top left big pole, and a pole off screen right.

You probably need to redo it's connections by shift clicking the pole.

Sorting? You're playing Angels with Bobs.

From the first image youll see Quarts is SI and from the third image (sorting) you'll see SI comes from Sorting Bobonium.

Faster inserters and bigger stack sizes seem to help waste less in these setups.

Its a bit less efficient but I just skip the belts these days.

I am playing 0.15 and I am wondering how I am supposed to use the bots without the advanced bot science. I don't know how passive provider check and storage chest can be made to do anything useful :roll: Add some roboports and they work with your inventory very well and of course they provide cover...

I actually did a very similar idea in one of my latest games. I had railwords style settings and I used regional ore depots. All ore from mining in an area went to a station. This station allowed transfer from 1-2 trains to much larger trains which trafficed it to smelting. In essence Only very larg...

There is a subtle barrier between complexity and efficiency. Often rail issues stem from trying to create something too simple. Rail in this game simply works best in a well planned environment. It is much easier to create artificial barriers by simply not giving yourself enough space or planning ah...

This is kind of a complicated subject so instead of rewriting a lot of stuff Im going to link you some great resources.

Was the train already in station?

Creative solution. I'm just curious what the extra mechanics are doing that a wire by itself couldn't do? It looks like maybe you are doing an iron plate between two numbers. Two decider combinators in series would do this as well. Wire-> plate < X -> Wire-> Plate >X -> Wire -> Station reads signal ...

What is your trigger to open/close the station? Coal Full? Iron Plate Full? etc?
