I just created my first scenario for Sandpatch, starting of at Hyndman track 02 heading for Cumberland. The Speedometer HUD shows a speed limit of 80 mph, which is clearly wrong. This speed limit is for passenger services. I think, see also my wishlist in the suggestions forum, the base object model for the Scenario Planner is oversimplified. You can set passenger or freight at the scenario level and this implies making passenger stops, but it seems not to imply the speed limits to be sett at the correct level for freight.
