That type of switch is called a double slip switch, a maintenance nightmare to do repair work on. It looks simple, but it's quite complicated in mechanical and electrical set up & controls for the signals as well.

It's possible to travel over it as if it was a simple "X," but also to enter one leg of the X and leave via the other leg that is on the same side. A very clever piece of trackwork. When the foreground train has departed, the one in the back can advance to the double slip and be switched to either the same track as the departed train, or to the adjacent track, behind the walking man.

The adjacent track switch seems to be four-way, as to which two directions it joins. It's sort of a Rubik's cube to set, I bet.
