At this time the planners prepare the design planning for the guideways and the engineering structures of the double-track guideway for the TRANSRAPID project Munich Main Station to the Airport, which allows a specification of the project costs as basis for economic efficiency analyses. The following report is based on these planning activities.

The German Federal Ministry of Transport, Construction and Urban development (BMVBS) has made the decision to advance the development of a new guideway for the Transrapid system. The companies Zublin, Zerna and Spiekermann were assigned to develop this new guideway, which means the start for a new generation of continuously supported guideways. It consists of a soil supported continous beam and true to size precasted concrete slabs with adjustable bearings in between. The installation of the system on the Transrapid test facility was completed in June 2006 and the type approval is expected during spring 2007.

The guideway switches for the Transrapid consist of a long bending beam supported at 15 m intervals as presented at the conference MAGLEV’2004 [Fichtner&Pichlmeier2004]. The forces from the vehicle’s support and guidance cause the bending beam to vibrate. Supported by the German Ministry BMVBS a switch with increased required lifespan for a Transrapid vehicle with increased payload (TR09) is developed. This demands a systematic analysis of the actual stress, taking vibration behavior into account. For this analysis two mechanical models are used. Firstly, analytical considerations and simulations using a Multibody System [Schiehlen1997] consisting of 37 elements are applied for parameter studies. Secondly, the stress situation is analyzed using a 3D-Finite Element model [Zienkiewicz1977] consisting of about 200 000 elements. Both models are verified by comparison with measurement results of the existing switches.
