Radio desk

The Dispatcher Radio Desk in the signal box, in brief - the full train radio is described in its own chapter.

The Dispatcher Radio Desk is the dispatcher's place in the train radio (GSM-R). It belongs in the signal box next to the track diagram.

Right click opens the radio: calls to single trains, a group call to everybody in the area, the emergency call, fixed messages ("Wait", "Proceed", "Stay put").
Order: the dispatcher allows a train standing at a signal at stop to pass it. A lock of the signal box no longer holds this train, and neither ETCS nor the PZB magnet stop it there.
Signal telephones that called in the last minutes are listed with the train waiting there; the dispatcher can ring back and give that train its order.
The desk is wired and always has network, no radio mast needed.
Area: sneak + right-click with an empty hand gives it a control area, like a control desk. Without one it serves the trains within 512 blocks.
Where no desk is staffed, the automatic dispatcher answers.

Everything else, from radio masts to Simple Voice Chat, is in the chapter Train radio.
