Aluminium Foam Sandwich (AFS) is now recognized as a material for the use in suburban railway systems. Recently there are two main fields of application. The first is the use as a kernel material for energy absorbing devices in case of impacts. The second is the use of the AFS special properties: this material is more and more an alternative to common solutions if several different demands must be fulfilled at one point. The fundamental design rules for energy absorbing devices will be presented. Some examples for realized buffers conform to the design needs will be shown. Finally a look into the future of the AFS application on the field of suburban railcars is taken. The basic demands for load-carrying parts at LRV are explained. Several problems are named and possible solutions are presented.
