Neupro - Realignment of production control at DB Netz AG

The modernization, construction and maintenance of signal boxes go hand in hand with ever increasing expenditure.

At the same time, aging facilities and decreased knowledge of the old technologies require pro-active obsolescence management. The NeuPro project is aimed at minimizing life cycle costs by way of modularization and standardization of signal boxes. It follows that signal boxes including array elements and other subsystems will no longer be manufactured and installed by a single supplier, but that respective components can be supplied by different manufacturers. SIGNON is supporting DB Netz AG in this endeavor with its expertise in system engineering and control and safety technologies. In cooperation with experts from DB Netz AG our engineers specify and model subsystems and their interfaces in compliance with a standardized procedure using SysML (Systems Modeling Language). Among other things, this will provide future SCIs (Standard Communication Interfaces) that allow standardized communication between the different subsystems of a signal box (e.g., between RBC and ESTW-Z) and thereby modularization.

Infrastructure data acquisition with SAT.engine in Belgium

As part of the necessary modernization and for the planning of ETCS, companies Infrabel and Siemens require up-to-date and meaningful data of the signaling infrastructures on the relevant routes of the Belgian rail network.

Between 2008 and 2013, SIGNON determined and recorded the track-related distances between track signals as well as respective track gradients for this project. It took five years to acquire the data of 1,700 km of track with approximately 10,000 infrastructure elements. To this end, SIGNON installed the SAT.engine tool on a traction unit and performed a GPS/GNSS measurement with synchronized video recording. After analysis of the data based on the synchronization of the GPS/GNSS data with the video data and having determined the track-related distances between the infrastructure elements, our experts were able to adjust even the output format of these datasets to the customer's wishes. Generation and provision of the datasets was fully automated. Siemens received a large data package, which, in addition to topological route maps also included element lists detailing the distances between signals, gradients as well as video recordings of the routes.

Our experts provide cross-system planning services for performance phases 1 to 7 and 9 regarding track/track infrastructure (together with BHI engineers), control and safety systems, 50 Hz power systems/points heating systems, OLA/OSE (with BHI engineers and CONROD) underground cabling and telecommunications systems.

Cross-system planning services for the first construction state of ESTW Oberhausen West

The scope of the first stage of construction of the new ESTW-Z Oberhausen West included the renewal of the control and safety technology in Bf Oberhausen West.

Additionally, telecommunications systems, points heating systems, power supply systems and the contact line/local control systems for Bf Oberhausen West were renewed or adapted. In this project SIGNON is acting from 2010 as general planner for DB Netz AG. For performance phases 1 to 7 and 9 SIGNON provided planning services for control and safety systems, underground cabling as well as for the outdoor installations/access routes to the ESTW module. Together with company Ökoplan, SIGNON was responsible for the planning of the points heating systems. Our experts provided further planning services for telecommunications systems, power systems (50 Hz) and contact line systems (OLA/OSE, together with CONROD).

Planning services for control and safety systems and underground cabling for ESTW Emmerich

During the construction of seven electronic signal boxes between Oberhausen Sterkrade and the Dutch border, SIGNON was in charge of concept and approval planning as well as implementation planning and the drafting of tender documents for both control and safety systems (LST) and underground cabling from 2006 to 2014.

The route is about 70 km long. The voltage change-over system (15 kV; 16.7 Hz to 1.5 kV DC) for the contact line at Bf Emmerich is a special case. A total of 295 signals, 138 points and 333 track vacancy detection sections is planned. The OCCs Oberhausen, Bocholt and Zewenar, adjacent to the ESTW-Z signal box area were adapted to electronic signal box technology.

Cross-system planning services for Syrian Railways (CFS)

SIGNON provided planning services for signaling technology in Syria from 2006 to 2010. For SIEMENS AG and Nokia Siemens Networks we provided planning services for ESTWs type SIEMENS SIMIS W for about 50 stations and OCCs of the Syrian Railways (CFS).

First, our experts drafted a planning guideline for signaling technology, which was then used as basis for all subsequent planning activities. In addition to the planning of signaling technology and outdoor telecommunications systems, SIGNON also provided planning services for underground cabling and earthing systems. For routes Tartous - Lattakia and Aleppo - Kameshli, with a total length of 850 km and 45 stations, SIGNON provided both the implementation planning for signaling and telecommunications systems and the concept planning for cable runs. Further services included the drafting of the tender documents for signaling, telecommunications systems and outdoor cabling. We assisted CFS with advice and support for track infrastructure, telecommunications and rail operations. Additionally, SIGNON provided the commissioning concept and assisted CFS during the construction phase by coordinating all subcontractors.
