Active support during implementation

Bringing engineering services to large infrastructure projects while meeting requirements

Our engineers and experts coordinate the contributions of a wide range of disciplines and trades. We coordinate the interfaces between management, specialist planners, operations and technology. We manage and monitor the construction side and the suppliers. Our many years of practical experience has made us familiar with railway-specific standards and administrative regulations such as the VV Bau-STE and we can demonstrably fulfill the procedures, defined interfaces, and roles in the management of railway infrastructure construction projects.

Our project managers have a solid background of experience and leadership in the rail industry and rail operations. Not only are they specialized engineers, but the actions they take within a project are characterized by economic thinking. Our network enables us to use trade specialists and EBA-approved experts in a targeted manner.

Our clients are national and international rail companies with passenger and freight transportation, the private rail industry, public clients, and their appointed general contractors. We also work in consortia with other companies.

Control, Command and Signaling (CCS)

quattron provides holistic operational management in the field of control, command and signaling technology (CCS), e.g. for the timely completion of commissioning projects. For this, we coordinate, control, and monitor the interfaces between the project participants (companies, sites, specialist consultants, specialist planners, etc.), the GC and suppliers. This is all possible thanks to many years of experience, knowledge of the relevant trades, and prudence.

CCS deals with the new construction, expansion and modernization of railway safety technology. It safeguards railway operations, serves to rationalize operational processes, provides meaningful relief for people in operation and helps to avoid hazards. Innovative technologies are particularly effective in CCS as the transition from conventional electromechanics to modern IT and telecommunications solutions offers a wide range of application and optimization potential. This is an area in which quattron has particular expertise and experience.

Telecommunications

In the field of telecommunications infrastructure, quattron offers a wide range of project management services for:

• Planning, specification and implementation of modern communication systems for railways
• Migration from analog to digital radio infrastructure and terminals
• Feasibility studies, profitability analysis, preparation of GSM-R in cooperation with quattron specialists
• Conception for the renewal of complex acceptances and commissioning
• Conception and implementation of complex acceptances and commissioning
• Construction of mobile radio networks for digital voice and data communication, such as for digital operational radio (BOS)

Telecommunications for railway includes the equipment, standardization and networking of various communication technologies and systems for rail vehicles and operating facilities. Services relating to the mobile radio standard extended to include railway-specific operating parameters, GSM-R (the Global System for Mobile Communications – Railway), are one of our core competencies.

Alongside ETCS and ETML, the GSM-R mobile radio system is the central technical component of the future ERTMS (European Rail Traffic Management System), which is intended to promote the interoperability of European rail transport. GSM-R is the mobile radio system for voice and data communication between vehicles, mobile terminals and fixed installations. It has been expanded to include safety-relevant functionalities and will also be the carrier network for ETCS Level 2/3 data, which enables remote train control, interlocking communication and train movement monitoring in addition to train protection.

Construction/Superstructure

In the field of construction/superstructure, quattron takes on project management tasks for the construction of new lines or upgraded lines with slab track for modern high-speed lines and conventional ballasted track. We control and monitor the necessary logistical and operational processes, coordinate the executing body, and manage a wide range of interfaces. We advise infrastructure projects on the effective design of key PM functions as well as on risk and quality management.

Electrotechnical systems

Electrotechnical systems include all traction current systems and the railway’s own network in the 16.7Hz range, the “normal” electric energy systems in the 50Hz range, direct current systems for the S-Bahn and EMC (Electromagnetic Compatibility). The pivotal point in the construction and operation of all types of electrical systems is always the safety of people, operational management and an adequate power supply.

In railway construction projects, there are always technical intersections with electrotechnical installations. We consider this field to be a genuine cross-cutting issue with great internal diversity and a prerequisite for reliable operational management. q4pm takes over the interface management here too as part of holistic technical and operational overall management.
