Small question about line management window colours

[Rollmaterial]

What does it indicate when line names appear turquoise in the line management window?

If I recall correctly, it indicates that departure slots are being missed (i.e. that convoys are not running to time). I need to update the documentation at some point, but there is such a lot else to do.

Ok, thanks! It also came to my mind in between.
