Mechanical vehicle & systems engineering – Our solutions

Development of suspended monorail vehicles

Customer: Kiepe Electric GmbH, Germany

Project tasks

  • Mechanical design of carbody, vehicle interior and running gear
  • Mechanical system integration
  • Manufacturing supervision
  • Homologation management

Our Approach

In order to overcome the first challenge of creating the optimized vehicle for this particular application, PROSE developed a vehicle body that is constructed from aluminium extrusion profiles.
Moreover, the continuous low floor and wide-opening doors guarantee efficient passenger flow. The new vehicles for the Wuppertal suspension railway also offer high driver comfort.

Customer benefit

Given PROSE’s extensive experience in developing mainstream and special projects of all kinds, PROSE’s development team was able to successfully meet Kiepe Electric GmbH’s expectations. Furthermore, PROSE’s intercultural experience and capabilities are highly appreciated, playing a fundamental catalyst role in the current manufacture of the vehicles in Austria, Germany and
Spain.

 

Design of a 100% low-floor tram

Customer: CRRC Sifang Co Ltd, China

Project tasks

  • Tram concept
  • Design and development of bogie and carbody conceptual design and development
  • Electrical concept
  • Mechanical system integration

Our Approach

In cooperation with the client, PROSE developed the system specification for the whole tram and several of its components. One of the most challenging tasks in 100% low floor-trams is the design of the bogie, which had to be both compact and offer a quality ride. Single wheels were the solution.

Customer benefit

The newly designed 100% low-floor tram is a major upgrade of CRRC Sifang’s tram portfolio. The integration of CRRC Sifang’s production know-how and related processes into PROSE’s design work means lower production costs for CRRC Sifang.

 

Bogie engineering in Finland

Customer: Transtech Oy, Finland

Project tasks

Our Approach

PROSE performed the entire development process at several locations. PROSE can perform all services, e.g. engineering, design, analyses and calculations, project management etc., at several locations, which cooperate closely, but, of course, the internal communications between the various locations is also always ensured.
The manufacture and the approval tests were performed by the customer, but PROSE provided active support.

Customer benefit

Thanks to PROSE’s extensive experience with the various vehicle components at its various locations, PROSE can offer comprehensive turnkey engineering services. Our customer profits from PROSE’s know how due to the close cooperation and the mutual visits.

 

Adaption of German maglev train technology for operation in China

Customer: Shanghai Maglev Transportation Development Co. Ltd (SMTDC), China

Project tasks

  • Modification of the German maglev train TR08 in line with the requirements of a commercial operation in Shanghai
  • Support of reassembly of vehicles in Shanghai, commissioning and the start of operation
  • Realization of a maintenance optimization program with quality control processes

Customer: Chemin de fer Montreux Oberland bernois MOB, Switzerland

Project tasks

  • Feasibility analysis
  • Mechanical and control engineering development
  • Detailed Manufacturing Design
  • Strength analysis
  • Support Approval

Our Approach

In cooperation with MOB, PROSE has developed the gauge-changing facility in several phases from a simple prototype to a complex series production system.

Customer benefit

From an early stage of the development of the gauge change system, PROSE supported MOB in approval issues. The complexity of the numerous interfaces between the gauge-changing facility and the vehicles, the infrastructure as well as the train protection systems of MOB and BLS were taken into account by PROSE through a close cooperation with the involved partners. From the conceptual design to the successful commissioning, MOB could be supported solutionoriented and target-oriented from one source.

Support for the approval of an automatic coupler

Verification of clearance between infrastructure gauge and infrastructure

Customer: Stadtwerke München GmbH (SWM), Germany

Project tasks

  • Support of the SWM project management in the technical evaluation of the results of the infrastructure survey
  • Interpretation of the results with regard to the requirements resulting from §18 of the BOStrab (German regulation on the construction and operation of tramways)
  • Recommendation of the measures to be taken
  • Preparation of the final report of the initial survey for the individual metro lines for submission to the technical supervisory authority

Our Approach

​With laser surveying, the existing installations are recorded with a precision that was previously impossible. PROSE supports the SWM project management in the technical evaluation of the results of the infrastructure survey. This includes the interpretation about the requirements resulting from §18 of the BOStrab as well as the measures to be taken. In addition, PROSE prepares the final report of the initial survey for the individual metro lines for submission to the technical supervisory authority.

Customer benefit

PROSE has experts with many years of expertise regarding the interaction of infrastructure and vehicle and especially regarding the clearance of the light area. This enables PROSE to advise clients on the interpretation of the applicable guidelines in case of ambiguous facts. PROSE was able to prove to SWM that several objects, which were initially classified as violating the clearance, do not pose a threat regarding the clearance. Thus, the customer could avoid a cost-intensive dismantling of these objects.

Support for the purchase of low-floor trams

Customer: Basel public transport authority (BVB), Switzerland

Project tasks

  • Capture customer wishes concerning vehicle technology
