German Unity Transport Project 8

 Nuremberg – Erfurt – Halle/Leipzig – Berlin

Slab track

The track for the high-speed line is of a higher quality. The sleepers are embedded in concrete or asphalt instead of ballast.

The advantage of this slab track is that it remains stable for decades, thus reducing the maintenance effort required.

Clothoid points

There is a world premier on the upgraded line from Leipzig/Halle to Berlin: super-long sets of points that allow speeds of 160 or 200 km/h thanks to their gentle curve (with a reduced radius from 16,000 to 6,100 metres).
Technical details mean the points require less maintenance. The points have a clothoid curvature. The longest set of points - in Bitterfeld - is 179 metres long.
