Steam Boston-worcester, P587 Boston South Station-framingham

While driving this train in journey mode (22nd run in journey) I constantly get a notification, that I should turn on battery power before trying to drive this train, everytime I touch the throttle, regardless if I reduce or add a notch...and how can I turn on battery power without access to the engine room in a F40PH? (Even though, I might be suspicious, that this train doesn't have been given the right start configuration in the editor).

 

You dont need to turn it on. Its already on its a bug. It also says that on boston to Providence loco as well.
