City blocks are ""best avoided"" because they complicate a lot the pathfinding for trains, which very often end up the limiting factor on (mega) base ... can deadlock and just from the picture it's difficult to be 100% sure with bridges that all chain signals are properly placed, but it seem like it ^^

Trains can only pass signals on the right side of the track, so for a bi-directional track EVERY ... one way track which will cause trains going the opposite way to show No Path.

True, but repaths already happen when the destination station becomes not-full, and this ...

My understanding is that this is a quirk of the pathfinding algorithm: the main line is shorter (since it doesn't have the curves), so trains prefer ... use of long mainline sections without using periodic non-chain signals, and non-chain signals mean you risk having trains park on your main ...

The train pathfinding system in Factorio has confused me for quite some time, and I think I've figured out why: sidings don't work the way I'd expect ... pair of sidings off of a long main line. The sidings have regular rail signals at their entry points, while the main line has only chain signals. What ...

... a sec, now the ship is considering "not moving" even though it is middle path to somewhere.


If the platform's thrust is paused/zero due to no fuel/oxidizer, but the platform is in the middle of a route, "moving to/from" signals are 1/2 as appropriate.

TL;DR
Space platform "moving from" and "moving to" signals should output desired state even when zero thrust is available.

Step 5: Some moments later, a train displays "No path to Starter1_Refuel[*]Coal". The name of the stop is the old name, despite the interrupt having been renamed. Just in case there might be a pathfinding issue, I check the train signals etc and can indeed make it get to the ...

Otherwise a train can path into that space in the time between when the ghost is created and the first bit of train is delivered resulting in a collision.

This sounds like 116952 or 119201 that were fixed in 2.0.16.
