Acceleration / Brake Indicator

I noticed positively that the BR423 has a colored Acceleration / Brake Indicator (Look the attached file).
It goes blue when accelerating, and it goes yellow when braking.

My wish is, to implement this feature to all German Trains.

 

They’re introducing a new accelerometer in the core update coming in the next week or two.

 

Where you got this Info ? In the Preview Stream of Boston Sprinter (Dev Build) its looks the same as it is right now.
