Wittenberger Steuerwagen/cab-car

Just a quick question about this, both the SIFA light and Voltmeter thing (that measures acceleration and braking) do not work. Is there something I am doing during set-up or is it just a bug. SIFA is enabled and the train works fine but it would be helpful having the.informatiojnoj Acceleration

 

I think you can fix it by resetting the simulation. (this button only works when you are not moving)

 

It is not working because of wrong train configuration:

But even with a right setup there is some bug - voltmeter will show everything on it's one side (acceleration or braking).
EDIT: You need to change KWS/ZWS mode both in the cab car and in the loco.

 

Thank you I will try this.
