On the Hohenzollernbrücke there seems to be the possibility to change the direction of the track.

I directed a delayed ICE wendezug from Deutz into track 7 at Köln Hbf (I know, that was a bad idea). But there seemed to be the possibilty to change the track direction on the Hohenzollernbrücke, so I thought the train should be able to use track 230 to return to Deutz.

However, I can not get the white arrow at track 230 to change. (I am using the direction change button on the "Group Buttons" window).

Are the direction change possible at all on the Hohenzollernbrücke?

As in Deutz is another dispatcher (though you have the generic panel for Deutz) you have to announce the train to neighbour by ZNP 801 and he will then change the direction.

ZNP 801: 100501+F5+230+B+Enter

Ah, Thank you, Helmut. :-)
