Something similar can be done both between dispatchers and between the dispatcher and the driver.
When the dispatcher presses the ZEW 1 button on the walkie-talkie, a similar menu pops up as for the dispatchers, so that there are such questions/answers as the track is free, the track is busy, wait, the platform is busy etc.
And the driver may have questions when pressing ZEW 3 whether the road is clear, how long I have to stand and something like that.
This will help different nations better manage routes and understand everyone.
