摘要

Spring element (1) made of a steel material for flexibly holding rails on a subconstruction has a cross-section (Q) which is matched to the local loads occurring during operation over the whole length of the steel material. Independent claims are also included for a system for fixing rails using the above spring element, and for methods for producing the spring element. Preferred Features: The shape of the cross-section changes many times over the whole length of the material. The size of the cross-sectional area changes over the whole length of the material.
