I have two suggestions.

I have two suggestions for the railway and statistics systems:
1. Optional railway light signals
I would like to have an optional railway light signal system.
The light signals should be able to control train traffic, for example by showing green when a train is allowed to proceed and red when the train has to stop because the section ahead is not clear.
The system should be optional. Similar to how players can choose to add overhead electric wires to railway tracks, players should be able to choose whether or not to add light signals.
Players who want to use light signals to control train traffic could enable the feature and build signals along the tracks. Players who do not want to use light signals could leave the feature disabled and continue using the current train system.
2. Optional dynamic sorting of statistics
I would also like an option for dynamically sorting the numbers in the statistics.
When dynamic sorting is enabled, the highest value should automatically be displayed at the top and the lowest value at the bottom. As the values change, the order should automatically update.
This feature should also have an on/off toggle. Players who want dynamic sorting could enable it, while players who prefer the current fixed order could leave it disabled.

You should make a separate suggestion topic for each so that members can vote on them independently.

1) And how would those signals be controled? You can already design part of rails as exclusive zone, so only 1 train can be there at all times.
