Method and system for profile or geometry measurement of a railway object, e.g. rail or switch or turnout component, e.g. frog, by using optical means measuring the object, preferably by triangulation or light sectioning, wherein preferably a correction factor is applied which is dependent from the horizontal and/or vertical oscillating movement of the measuring train and which correction factor is applied to computer calculations for a geometric feature of interest of the measured track object or an associated track object, which correction factor is determined by the use of additional optical means measuring the object.
