Question About The Dispatcher Scenario

So there is a scenario 'Day of the Dispatcher' on the Riviera line.

Now i do wonder how this is IRL.
Isn't it usually the guard of the train that gives the go signal? Is that a separate job in the UK?

To dispatch the train, you have to blow a whistle, would it not be easier to use space bar instead of going to a location on the platform to a marker that you have to click?

 

Dispatch is by platform staff at manned stations in the UK, I believe. (I know someone will correct me if I'm wrong).

Liam had to use scripting for the dispatching and a marker for the dispatch corridor, hence why you dispatch on mouse click, I believe, but he can correct me on that if I am again wrong

 

How do you actually blow the whistle?!

 

control-1 to show where you have to go.
On console i don't know

 

Thanks will try that (on PC). Why the key to sound the whistle is Ctrl 1 is beyond me. How would anyone figure that out given there is a horn/whistle key shortcut!

 

whistle is spacebar or 'N'
