Fast Lane Tool for train tracks

Ahoi Captains!
I think the game needs a Fast Lane Tool for train tracks like the No Stop Zone Tool.
With the FL Tool you can force the trains to take a specific route. The trains take usually the shortest way, but this isn’t always the fastest way. The shortest way can have a slow switch or corner in it. In worst cases the train driving through a station and blocking it if they have to stop, because they can‘t get back on the main track directly.
Or they take the track with intersections and not the bypass without intersections.
With a Fast Lane Tool every train knows where to go, doesn’t matter to which train line it belongs to.
Vote for it!
