Operating Passenger Doors With The Emd F125 Locomotive

I seem to notice that there are no visible buttons or switches that allow to open and close passenger doors inside the F125's cab. When playing the F125 Introduction, I am not shown an objective marker to indicate their presence; I seem required to use a bound key.

I suppose this is modeled on the real locomotive. But how do its conductors operate passenger doors in real life then? Is it done through the onboard computer? Is there always a second operator riding in the back cab where door control buttons are located?

 

It'll be operated by the conductor in the coaches.

 

So Metrolink passenger services are always a two-man operation? Seems surprisingly costly.

 

Union.

 

I see! xD Good for them.
