PROSE BrakePASS - Traceable and automatically documented brake tests

For railway operation safety, the correct execution of the brake test is highly important.

Problem

For railway operation safety, the correct execution of the brake test is highly important. An essential component of this procedure is the check as to whether the brake control signal reaches all braking systems of a train. Reliability can be considerably increased through an automatic documentation of this testing step. PROSE offers a novel solution using state-of-the-art technology by means of which the reliability of the execution of the brake test can be increased.


Our solution

PROSE developed the BrakePASS system to support the operating personnel.


BrakePASS consists of three elements:

  • The BrakePASS test head is set onto the coupling of the brake pipe at the rear of the train before the brake test and remains in that position during the brake test. BrakePASS has a radio connection to the operator‘s smartphone.
  • The function is controlled using the BrakePASS app. The app receives and processes the data of the brake pipe. The operator immediately receives a check-back signal.
  • Data are transmitted via the mobile network to a database, which provides online access.

Customer benefit

  • With just a few actions, the brake test is safer with BrakePASS.
  • The handling of the train is not influenced by the use of BrakePASS.
  • The continuity of the brake pipe is automatically determined and documented.
  • With BrakePASS, the employee has additional safety to perform the brake test correctly.
  • The data are documented for later evaluation.

For further information find us at: www.brakepass.one

Gauge-Changing Bogie - EV09

The Montreux-Berner Oberland-Bahn (MOB) entrusted PROSE with the design of gauge-changing trailing bogies.

Project specification

The Montreux-Berner Oberland-Bahn (MOB) entrusted PROSE with the design of gauge-changing trailing bogies. The development engineers used MOB’s construction and operating principle as a basis for the design of the bogies, this makes it possible to change the gauge of the bogies by running them over a fixed axle- gauge changeover facility at low speed. The change from meter gauge to standard gauge and vice versa is facilitated by two half frames, which can be moved 435mm sideways relative to each other and are equipped with independent wheels. This construction principle had to be realized in the bogie design. Further challenges for PROSE were the compensation of the different platform heights for standard gauge and meter gauge by way of two supports of different heights in the bogie traverse as well as the customer’s requirement that it had to be possible to fit the new bogies under existing car bodies and under new car bodies.


Our approach

During the design phase of the bogies PROSE performed structural analyses, calculated the running dynamics and analyzed different alternatives to optimize the components and the bogies. Wherever possible, PROSE’s engineers used components proven and tested by the railway sector such as air spring and vehicle anti-roll bar to minimize the risks that are generally inherent to new developments. If this was not possible, e.g. in case of the axle-gauge changeover facilities, PROSE used positively driven mechanisms such as trunnions and positive interlocking devices. By preferring simple mechanisms and standard components, PROSE was able to reduce the number of spare parts to be stored and thus reduce the maintenance costs. The bogies were developed in close collaboration with MOB. PROSE defined the design requirements for the axle-gauge changeover facility by way of computer simulations and calculations and MOB constructed it.


Customer benefit

Thanks to the innovative gauge-changing bogies it will be possible for MOB’s passengers to ride on the GoldenPass trains between Montreux and Interlaken without have to change trains at the location where the track changes its gauge. Thus, the offering and the attractiveness of the line is improved, which has a positive effect on the tourism in the Berner Oberland and at the Vaud Riviera. The passengers benefit from the new services and enjoy higher ride comfort.

New suspended monorail vehicles for Wuppertal

The suspended monorail of Wuppertal and its vehicles are an integral part of Wuppertal’s cityscape and its cultural heritage.

Project specification

The suspended monorail of Wuppertal and its vehicles are an integral part of Wuppertal’s cityscape and its cultural heritage. By running above the river and the streets, the suspension railway acts as a central artery of public transport in the whole city. The 31 new vehicles are to replace old trains that have reached the end of their service lives. The general contractor Kiepe Electric GmbH entrusted PROSE with the comprehensive mechanical design and the system integration of the new vehicles. PROSE was confronted with two main challenges: firstly, the new vehicles for the suspension railway had to be compatible with the existing infrastructure, which imposes extremely restrictive maximum values for the dimensions and weight of the vehicles. Secondly, the new vehicles had to fulfil the passengers’ requirements for modern comfort. Thus, comfort features, such as passenger information system and air conditioning, had to be integrated.


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. By implementing this combination, the end vehicle body only weighs 5.4 tons, including the driver’s cab. All four bogies have two-stage supensions and are powered by three-phase asynchronous motors which guarantee smooth running. Through the use of regenerative braking systems PROSE is able to achieve high energy efficiency and low wear and tear. To meet the passengers’ comfort requirements, PROSE implemented a continuous row of windows conveying a dynamic appearance, which offers a bright and comfortable ambience to the passengers. Another highlight is the fullheight panoramic window at the back end of the vehicle. 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: an ergonomically designed driver’s cab is separated from the passenger compartment by a transparent wall and equipped with modern touch-screen commands.


Customer benefit

Not only is compliance with significant standards of fundamental importance for the successful realization of this unique system, but also the ability to contribute to the definition of these standards, to proactively propose an optimal solution, discuss it constructively with all parties involved (including the end customer, safety authorities and suppliers of systems and components) and finally implement it. 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.

The world’s first biogas-driven train

The biogas supplier Svensk Biogas wanted to prove that a train can run on biogas (methane gas).

Project specification

The biogas supplier Svensk Biogas wanted to prove that a train can run on biogas (methane gas). The customer supplied a diesel train to be converted into biogas propulsion and entrusted PROSE with the management of the development of the first biogaspropulsion train in the world from A to Z.


Our approach

PROSE was in charge of the project management throughout the project. Firstly, a feasibility study was conducted in order to identify the technical requirements, to define the project schedule and to fix the budget. Then a safety analysis was performed to identify suitable traction motors for the fuel system and a solution that fulfils all safety requirements. PROSE successfully overcame the challenges such as the limited space available for the fuel tanks and the compliance with demanding safety requirements. The existing control system was adapted to the new biogas engine and several safety features were integrated into the system. Moreover, PROSE made a test plan and tested and verified all critical parts of the propulsion system for successful commissioning of the train. PROSE prepared the technical documentation needed for the homologation of the vehicle, the installation instructions, the maintenance documentation as well as the training of the drivers and the maintenance staff. PROSE finally performed a study for the maintenance workshop for the additional safety installations and checked the results before the biogas train was put into service.


Customer benefit

PROSE supported the customer along the whole process, from the feasibility study and the identification of the technical requirements through the adaptation of the existing engine to biogas to the homologation management and the maintenance optimisation.
