Since 2012 it became apparent to public transport operators, that a concious decision is necessary between purchasing and installing a new generation of TVM (ticket vending machines) and retrofitting the current machines.  Every business case we prepared so far with a customer showed clearly: To keep the current machines, open the interfaces and source of the software (solving vendor-lock-in) with a retrofit is commercially and time wise always favorable.

With the successful conclusion of the first retrofit projects, from POS- (point of sale), passenger information-, to many other equipment it became apparent that the full potential of retrofit has by far not reached its limit.

In the meantime, many notable public transport operators have become customers of our retrofit solution, we are confident, that we can convince even more companies to go in this direction. For this, feasibility studies and solid cost estimation for hardware and integration into the customers systems are carried out. As soon as we are allowed to inform about the next concluded projects, we will do this here.

Some next projects are currently in preparation and in roll-out.

This week, we could celebrate our first tech-event about the railway infrastructure diagnosis vehicle gDFZ from SBB. Joel Casutt, Florentin Marty and Patrick Wernli led the audience with over 200 guests through the vision, how the Zentrales System works, collects data, computes data makes them ready and visualizes them, as well as which sensors are utilized and what first learnings about fault detection on the rails could be observed.

This year, Supercomputing Systems is its first time present at the Innotrans with our own booth. You are very welcome to come by between Tuesday 18. September and Friday 21. September in Berlin to discuss with us recent projects, innovative technologies and project approaches.

SCS booth – Hall 2.2, booth 207 (SWISSRAIL Pavillon, 1. Stock)

Projects that we will showcase at the event:

  • Refirt of partially obsolescent systems on the example of ticket vending machine refit (including Front- and Backend)
  • Highly available and distributed systems on the example of the SBB ZKE-Netz (wayside train monitoring system)
  • Machine learning and computer vision on the example of advanced data analytics

We are looking forward to talk to you. If you want to schedule an appointment, contact us via e-mail to:

By 2014, The tpg and SCS started a collaboration for the upgrade of the 500 ticket machines, with the aim to develop a new sales software and to renew certain components of the sales systems.

Just six months after the start of the project, the first prototype started dispensing tickets at Geneva’s Cornavin Train Station. Four months later, in December 2014, the rollout was completed by 100 machines.

The modifications have enabled the tpg to halve both the time of the sales transaction and of maintenance operations. The availability of vending machines has improved massively and is now over 99%.

During the next stage of collaboration, the solar ticket machines will be reengineered.

The safety and availability of SBB railway infrastructures is ensured by the Infrastructure Monitoring business unit. SBB requires a “towed diagnostics vehicle” (gDFZ) to fulfill this duty and at the same time to provide an enhancement to the existing self-propelled diagnostic vehicle. The gDFZ can also measure the vehicle dynamics and overhead line. When in use, the gDFZ is drawn in a train composition consisting of a locomotive, a braking and a control car.

The central system forms the heart of the new vehicle. It not only adopts the interaction with the user, but also the analysis and the persistent storage and display of all measurement data.

The SBB has accepted the tender from SCS for the development of the central system (hardware and software). The successful concept in the public call for tender combines for the first time modular measurement equipment via open interfaces with the technology of a modern data centre and integrates them into a rail car. This flagship project meets all the essential features of an “Industry 4.0” application.

The Microservice architecture allows a modular, flexible, extensible and highly scalable solution. The result is a clear and extensible software environment, which is extremely well suited for further development over the entire life of the gDFZ and which can also be operated efficiently.

SCS also takes on the role of integrator for the overall system. System integration is the key success factor for the entire project. The chosen solution therefore supports the integration of all current diagnostic and support systems through a clear and systematic approach and through open, transparent and scalable system architecture. SCS has extensive experience both in the field of open systems, the integration of third-party systems and the development of “mission critical applications” including maintenance and support throughout the entire life cycle (Life Cycle Management – LCM), for example with the REGA communication system.

We are delighted with this award and the prospect of working with SBB and the suppliers of the other work packages, peripheral systems and vehicle modifications.


Background information on the application:

The SBB infrastructure monitoring business unit is responsible for ensuring the safety and availability of railway infrastructure in compliance with the applicable regulations. The services provided by the monitoring unit are fulfilled using a mix of human expertise (route inspectors) and machine-determined diagnostic and prognostic data (Measurement and Diagnostic Technology). In the medium term the proportion of machine performance will increase due to the expansion of the industrial monitoring of the network and the commissioning of new high-speed lines (Gotthard and Ceneri Base Tunnel GBT/CBT).

Measured test runs are state of the art in railway technology and essential for professional investment management, particularly in the track and traction current asset classes. The measurements in the field of driving technology are mandatory because of the legal and regulatory requirements (including R 22070). Reliable, consistent and meaningful measurement data also provides an important input for short-term diagnostics (monitoring), preventive maintenance and the prognosis of the substance preservation. They form the basis for the medium and long-term maintenance control of the asset classes.


The company Jöhl + Köferli AG offers tailored radio-transmission solutions. Supplemented by a control system, a central communication infrastructure for public transport emerges.

The comprehensive and reliable radio coverage of an area is always hampered by topographical and structural barriers. The single frequency radio network technology designed by Jöhl + Köferli AG solves this problem by using many spatially separated base stations, which guarantee full coverage of the concerned areas. The base stations emit information, which is synchronised on the same frequency. Thus, the frequency spectrum is used economically, allowing the use of simple terminal devices.

The voice connection between the control system and the base stations is achieved via voice-over-IP. The GPS-based synchronisation, designed to keep a precision up to microseconds, allows the simultaneous emitting of the signal at all base stations.

Supercomputing Systems AG (SCS) has developed a universal hardware platform, which is used by the control system (TMC) as well as the radio transmission site (BSC). It is based upon a multi core ARM Cortex A9 processor and the Altera FPGA technology.

Moreover, the Linux software and the FPGA firmware have been developed for the Voice-over-IP communication, the FSK modems as well as the call decoder.


The platform can be used for the integration of a variety of other signal processing tasks.

Jöhl + Köferli AG use the module in a flexible and universal way and expand it according to the different requirement of the public transportation companies. Via a web-based configuration panel, adjustments can be quickly performed.

The new 12/13 timetable brought major changes for public transport users in the Canton of Zug: Ring zones were converted into area zone systems. This took place as part of the integration into the ITV Z-Pass Corridor Zug/Schwyz. From the logistical point of view, this meant that a range of completely new products, as well as new user interfaces had to be activated across 150 systems during just one night.

The automated ‘Big Bang’ switch worked perfectly thanks to intensive tests in the run-up. The SCS team only needed to intervene via remote access on one single ticket vending machine during the night.

The new system not only makes our customers happy but also makes us – the developers – proud!

ZVB Userinterface Ringzonen   becomes    Userinterface im ZVV Stil

Userinterface im ZVV Stil

The preparations for the 12/13 timetable change are running at full speed. Good progress is being made on the software development for the new user interface in ZVV style. ZVB’s 2013 product range is being created in close co-operation with tariff specialists. The tariffs of SBB, ITV Z-Pass and TV Zug are being bundled into one range. At the Zugermesse (Zug Trade Fair), the public took the opportunity to have a closer look at the “new” ticket vending machines and the upcoming area zone product range. We, the developers, see the positive feedback to mean one thing: “Dress rehearsal successful“.

Userinterface im ZVV Stil

The ticketing system for ticket vending machines for Zugerland Verkehrsbetriebe AG (ZVB) has been approved and is being rolled out. The development lasted from the specification in early 2010 until the field test phase in the first quarter of 2012. Hardware control and a retailing GUI were developed during this time in close cooperation with the client, ZVB. An interface module assumes the control of the special devices and interfaces. The module was especially developed for this project by SCS.
