Abstract
A guide rail for an elevator system may comprise at least two rail elements that together form a guide rail portion having a functional running track that extends in a travel direction. Each of the rail elements may be connected to a shaft wall of the elevator system. Furthermore, the at least two rail elements may be adjacent and spaced such that the at least two rail elements can thermally expand freely in the travel direction. Additionally, the at least two rail elements in a region of the functional running track may have mutually opposite borders that have complementary profiles. An arbitrary cross section of the guide rail portion perpendicular to the travel direction in the region of the functional track may run through at least one of the two adjacent rail elements.
