Just got the game today and i’m trying to essentially recreate the DC metro but I can’t figure out how to cross the potomac. The track needs to be a certain height or depth across the river, but then the incline is too steep to get to that height or depth from the building restrictions on the Wharf. How can i go from track at -10 M minimum to abrupt 5m or above when the train goes from land to above the river?
