Random Exceptions For Service Mode.

If there's random exceptions in service mode, it would add more realism improve the experience of service mode. Chance of those exceptions is small, of course. I'll list here some suggestions

-Fallen trees on the track.
-Electric failures (on train line power or overhead wires.)
-Construction works

 

Or Zusi style \o/ ** we can choose % level of irregularities

 

It would be really cool if we had dynamic gameplay indeed. It would be funner to drive services and give variation to the game
