Two switches with movable frogs seen in Lövenich (on Cologne-Aachen) on 24 September 2001. In the foreground it is clearly visible that the frog closes the gap that is left open at switches with fixed frogs. Also note that there are no flangeways. At the switch in the background you can see that there are two distinct groups of actuators for the frog and for the tongues, and also two position indicators. The sleepers of the crossover track are divided in the middle and connected with something that seems to be elastic. Also the rails are fixed on the sleepers different in the switch area, compared to left track in the background. As far as I know, these switches have a turnout radius of 1200 m and can be passed with 100 km/h on the diverging route.
