Signal Tutorial / Book

[Weißbrot]

Since there is no explanation in SimRail itself i think a tutorial mission for the polish signals would be a very nice addition especially for new players like me it would make the learning curve less steep, i personally found a good picture with the signals and short explanations but still an indepth tutorial mission covering all polish signals in SimRail would be great.

Or a window/tab/little book (similar to the time table book in EN57) you can open in MP or SP independent of your role where all signals are shown and explained.
