Adjust DCC throttle between -1 and 1. This command can only be used prior to one of the driving commands JustDrive, DriveViaTrackmark, DriveViaTrigger, DrivePastJunction, and CoupleAhead that are available on DS. Note that the negative throttle values drive the train in the opposite direction.
NOTE: This command is identical to SetDCCThrottle command used in TRS2004. In this update, the command description is updated.
