Driving a 2,200t freight train safely down the Brenner Pass railway track

The project is part of an extensive analysis regarding the safety of the operation of heavy freight trains for an Italian based freight train operator, in which PROSE was commissioned to analyse the longitudinal dynamics of different train configurations in specific brake scenarios on the transalpine Brenner Pass railway track.

Project specification

The project is part of an extensive analysis regarding the safety of the operation of heavy freight trains for an Italian based freight train operator, in which PROSE was commissioned to analyse the longitudinal dynamics of different train configurations in specific brake scenarios on the transalpine Brenner Pass railway track. For this purpose, extensive multibody simulations were performed – during which the forces in the buffers and draw gears as well as the wheel/rail forces were observed and examined.


Our approach

When it comes to the maximum forces in the buffers and draw gears, PROSE determined the most sensitive setup in terms of train configuration, point of brake initiation as well as failure mode. This was achieved using numerous variations which lead to a trade-off of modeling depth, degrees of freedom as well as numbers of variations.

This brought along challenges such as identifying the most sensitive case on basis on a limited number of simulations. Another challenge was that of developing a buffer and draw gear model that combines an accurate picture of the reality with a suitable numerical efficiency.

PROSE overcame these challenges by using a simulation model, which follows two steps in line with the requirements; but also by choosing the starting points of the variations with great care and profound experience.


Customer benefit

The results show that in some cases, the originally proposed train configuration leads to high forces in the buffers and draw gears. Given this, more suitable configurations have been proposed, that in addition lead to cost savings.
PROSE also developed a more realistic model for the buffers and draw gears. As a result, the quasi-static curve negotiation can be simulated more accurately than it is the case using standard solutions.

Driverless Operation Feasibility- Waldenburgerbahn

Baselland Transport AG (BLT), as the new operator of the Waldenburgerbahn, wants to check the feasibility of automatic and/or autonomous operation as part of a complete renewal.

Project specification

Baselland Transport AG (BLT), as the new operator of the Waldenburgerbahn, wants to check the feasibility of automatic and/or autonomous operation as part of a complete renewal. The aim is a gradual introduction of innovative technologies to secure future-oriented investments. The results of the feasibility study are to be integrated in the preparation of the tender for the new rolling stock, as well as in the parallel tasks of project planning of the infrastructure.


Our approach

A diversified broad-ranging taking phase as well as a separate phase for in-depth analysis were carried out before the feasibility phase. This ensured the conclusion of well-founded statements. During the first phase, a market overview was carried out together with a detailed description of the planned infrastructure – which ensured the achievement of the range required. The next step was creating the additional depth required by using standard technology and safety analyses. After consolidation, various variants were developed and evaluated during the feasibility phase. In coordination with the Federal Office of Transport (FOT), the best variant was selected and subsequently specified by proposed implementation measures.


Customer benefit

Thanks to PROSE’s structured approach, BLT received a well-founded result based on a diversified analysis. During the realisation of the project, BLT already received an overview of the current state of the art autonomous transport systems and of present projects. In the end PROSE developed a coordinated proposal for a step by step introduction of autonomous operation, as well as further steps required for implementation, which were co-ordinated with the FOT.

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.

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.
