So, I've just been experimenting with the new greedy signals. Can I confirm with you guys what they do, just to check I'm right! ;D
Greedy signals are the same as pre-signals - except they don't demand to reserve the next two blocks, they try to reserve the next two blocks. If the second block is already reserved, they just reserve one block instead.
Can't actually think where this would be useful - any suggestions? Nice to have new stuff to play with! 👍
Yes, they work as you describe. This can be used e.g. for overtaking stations, or where two lines join, and you want to give priority to one of them.
Place several of them in a row and experiment with that ;)
