The basis for PROSE's task was a basic concept with the functional principle elaborated by the operator MOB. PROSE Ltd. revised, optimised and completed the preliminary design by means of design studies, stress analysis and running dynamic simulation. This resulted in a final design with manufacturing drawings.

The innovative principle for changing the track gauge, i.e. the lateral movement of the two bogie half frames from meter gauge to standard gauge and vice versa, was analysed be means of computerised kinematic simulation and dynamic calculations. These results were the inputs for the design of the bogie and of the track gauge changing facility. MOB disposes now, apart of the two prototype-bogies, of an operative track gauge changing facility on which functional and endurance tests can be performed. The facility is currently installed at the premises of MOB in Montreux but it will be later relocated to Zweisimmen.

PROSE Ltd. achieved a further milestone in its key competence in bogie design by the successful completion of this development project for the track gauge changing bogie for MOB.

PROSE Ltd. is an engineering company in the field of railway rolling stock with about 40 employees, performing running dynamics and structural analysis, designing refit projects, performs vehicle testing as accredited testing laboratory and consults in the field of noise reduction, procurement management and maintenance optimisation.
 

 

 the motor bogies for the diesel-electric locomotives Gmf 4/4 for the Rhaetian Railways (RhB).

The 4 ordered locomotives shall be in operation in the infrastructure department of RhB, mainly used for heavy track construction and maintenance trains as well as trains to remove snow from the track.

The bogies have to satisfy the high requirements of lines with a lot of narrow curves of the RhB lines in the Swiss Alps as well as to run with 100 km/h. In addition special attention has to be paid to a reliable operation also under strong winter conditions.

PROSE develops with 40 employees bogies, performs running dynamics and structural analysis, designs refit projects, does vehicle testing as accredited testing laboratory and consults in the field of noise reduction, procurement management and maintenance optimisation.

 

We tested the vehicle concerning running dynamics, brake and wheel slide protection system intensely.
 
PROSE already tested vehicles of the same platform before in the Netherlands and in Switzerland which achieved the national homologation. The accredited testing laboratory of PROSE has the necessary specialist knowledge and the experience, which is required for the homologation of such special vehicles.

With the goal to offer our customers even more complete service out of one hand, we enlarged our portfolio per January 1. 2010. With the acquisition of the laboratory for interference currents tests from Bombardier Transportation (Switzerland) Ltd we now are able to also measure and document this important parameter of a vehicle accordingly. With Herbert Biri and the needed [Ueli Ritter] testing equipment for this specialized department, we now cover together with the existing testing laboratory, the range from measuring brake performances, comfort levels, noise, ride quality and security to interference current needed for the homologation. Our customers can now obtain these services from a single source of PROSE.

To be ready for the needs of the re-emerging market, we are expanding by February 1. and March 15. our engineering team in the field of strength analysis and running technique with two experienced engineers, who have a wide experience in the development and design of freight wagons. For our design team, we were able to win with Gregory Völkening a professional with many years of experience in the management of engineering projects. Thus we have those skills necessary to to be able to.quickly and comprehensively respond to the requests and needs of our customers.

We extensively tested the train in driving comfort and running dynamics, in the
pleasant environment of the "Bündner Mountains". These studies are an important step
in the delivery and commissioning of this new train. We also support your prject on the
home straight.

Visitors to suissetraffic could find a very varied programme with a representative cross-section of current innovations from all sectors of public transport. Over 160 exhibitors occupying 20,000 m2 of space, fascinating conferences and a well-supported Symposium made suissetraffic this year's central market platform in Europe.

PROSE has successfully achieved the certification to perform welding work within the range of certification level CL4 according to EN 15085-2.

Der neue PROSE Geschäftsbereich Noise Reduction & Environment führte im Januar 2009 erfolgreich die erste Geräuschemissionsmessung nach der Richtlinie 2000/14/EG durch.

Rechtzeitig zur Inkrafttretung der neuen Maschinenlärmverordnung (MaLV) für die Schweiz im Sommer 2009, ist PROSE bereit, die entsprechenden Hersteller solcher Maschinen mit den notwendigen Messungen bedienen zu können.

Herr Christian Czolbe freut sich, wenn er auch Ihnen helfen kann und Ihre Maschinen erfolgreich zur Zulassung führen und die notwendigen Zertifikate ausstellen kann.

The division under the lead of Christian Czolbe dedicates itself primarily to the improvement of the noise pollution of our population. Noise studies are compiled, studied environmental condition in connection with the railway and prepared solutions.
