I see Pantograph up/down commands for DCC, how does it operate in DCS? Thanks.
Remember, MTH often copies and pastes some technical information such as CV location. That does NOT mean your engine is equipped with that feature.
30-XXXX-1 series- AKA railking may not have the same features as a Premier 20-XXXX-1.

Again, the Railking being a smaller and often less featured unit, I can find no such parts breakdown or manual instructions indicating it actually has motorized pantographs.
