Thanks for the suggestion.
I tried this solution.
Sadly the live map is lagging a fair bit behind the game when i use it.
The live map is working best for me when zoomed in fully just not timed okay.
When i try to zoom out then the tracking of my trains position becomes even worse with lag.
Also i still would have the drawback that i need at least 2 monitors to use it or need to alt-tab out of the game to see the other window and by doing so again moving away from the train drivers view.
That is something i am actually not willing to do unless i have time like being stopped in station to do so.
