Is there a particular way you need to set up the 710 in the editor in order for it to start on AC or DC mode. Tried setting it up with Pantograph on 25kV, at Willesden Yard, but when I run play in editor, its still sat there with Pantograph lowered. In order to change over to DC, assume you would need to end a service and create a new service with the new power system set up.
