The RUF system will be implemented as a network of guideways. A typical mesh size will be 5 x 5 km, so a typical commuter will use 3 sections of the rail. At every junction, the speed is reduced to 30 km/h. The top speed between junctions can reach 200 km/h, but typically it will be 150 km/h when the mesh size is 5 x 5 km.

The reason for this speed reduction during switching is partly that the the safety has to be extremely high in an automated system, partly that if the speed was any higher, the radius of curvature would be much higher (it goes with the square of the speed). In an existing city it will not be possible to find room for soft curves. At 30 km/h the comfort criteria will allow for a 26 m radius of curvature.
