  6. Eddy-current Brake on an ICE 3

  7. The Role of the Infrastructure Operator Solving conflicts between train movements (dispatching) Providing safe track sections to be used by train movement Issuing movement authority to enter a track section

  8. Core Safety Functions in Rail Traffic Control Safe train separation (avoiding crashes between following and opposing movements) Safe routes on turnouts and crossing (avoiding accidents on movable track elements and intersections) Automatic Train Protection (ATP) (preventing trains from violating authority limits)
