The side sway from the lateral acceleration now goes off only on a track with a sideways value, and the random jolts on one with a vertical or a sideways value. Dips at the rail joints and cross level alone replace neither. On a switch it goes by the path set and what its joined tracks allow. An edit in the editor also rebuilds the other switches of a joined group with the tracks they meet, and the tracks of a rail run whose joints moved. Removing a track does the same. While dragging, the tracks further off wait until the drag ends. The clatter of a bogie's axles was right: the followers stand at the pivots and the offsets are the places of the wheel sets. The misleading name goes. Also what Sonar had left: a parameter as a span, a const method, a struct and its member apart, commented out code, and a function of the grading tool split, with the same output.
