I notice there are crossings on Sherman Hill that when a train approaches a crossing one side the gates go down when a train approaches a crossing but on one side they go down when the train is on the crossing rather than when a train approaches.
I call this an improvement over crossing gates that never move at all. Can you be specific about the location?
Wait a minute ... wait a minute! How can you tell whether crossing gates move or not (on any route, not just Sherman Hill)? Please reveal which view you were using when you saw the gates move (in cab, head out, 2, 3, etc.).
