Route Dresden to Chemnitz. Driving from 766 cab car. Scenario "Better Late Than Never" as part of Journey Mode. Issue: After resuming save game unable to take power with the throttle. Throttle is not power locked with indicator on the HUD showing white. Action Taken: Shut down cab completely and restarted systems. Fault persists - throttle notches shown in white but train not moving and no positive Kn displayed on the HUD. Other factors: Running with SIFA and PZB inactive, as a precaution pushed both reset keys but this did not resolve problem. Effect: If this scenario cannot be completed in one setting, unable to advance in Journey Mode. Possible workaround: Close down 766 and attempt to push the train to destination with the 143. (Effiacy TBC). Edit: Workaround okay, able to power up the 143 and propel train at reduced speed.
Uncouple 143 from 766 and couple it back. This will give you power again in the cab car when resuming a saved game.
