What did you do?
I placed a ghost rail signal on a ghost rail.

What happened?
It did not attach to the rail (Blinks green/yellow/red)

What did you expect to happen instead?
Attach to the rail as if I placed it (ghost placed or not).

I made a video that also shows that shows this issue and that ghost signals can be placed ANYWHERE and remembers the orientation of the last correct placement.
I would suggest:
- Disable the ability of ghost placing signals anywhere except correct placements (same behavior as placed by hand)
- (Cherry on top) Enable ghost placement of signals on ghost rails

Currently you have to wait until the rails were built by the bots before placing the signals.


I don't think my logs are necessary since this is a gameplay "bug(?)". But sure will provide if necessary.

The problem is, that you built the signal in the wrong direction.
When building signals no non ghost rails, the direction of the signal is selected automatically to match the nearby rail (if more rails are nearby, pressing R switches between the variants).
But when building next to ghost rail, this mechanism is not there, and you can build the signals in opposite direction, thus the signal doesn't connect, as it expect rail on the other side.
If you try to rotate the signal and build it, you will see that it will connect.

I agree, that this is little bit weird, so I changed for 0.16.31, so rail signal direction auto-selection takes ghost rails into consideration.

Thanks. I always found it hard to see which direction a ghost signal was facing and if it even was allowed at a certain spot.

Did you fix the placement of train stops to consider ghost rails too?

What about placing chests or inserters next to ghost rails or ghost stops? Will the helpful white boxes appear showing where train cars will be?

This thing was only done on my laptop and never actually pushed to our code base. I discovered it today, so I pushed it for 0.17
