Restoration of faultless track geometry is the purpose of track maintenance work. Modern maintenance machines measure track geometry by measuring systems and change track position by lifting and slewing. The improved geometry is fixed by tamping. The usual way of operation is the automatic mode. Fully automatic lining and leveling methods use chord systems which are moved along the track and find a smoothed curvature within the length of the system. High speed track requires excellent geometry and sufficient strength. Research and development to meet the requirements are described.
