A double slip switch is NOT a crossover. A crossover is a connection between two ajacent tracks. A double slip switch is crossing (not a crossover) that allows movements between routes. You can make simulatenous parallel movements through a crossover (both trains running normal). You cannot move two trains simultaneously through a double slip switch.
