SIGNON has developed a comprehensive risk assessment method for safety at light rail stations.
This method was applied prior and in the course of the redesign of LRT stations in two German light rail and tram systems, in Frankfurt and in Darmstadt. The dedicated methodology was based on commonly applied standards (EN50126 and ISO31000) in rail systems provided a systematic, logical and transparent approach to identify threats and assess associated risks. The light rail stations in Frankfurt were both to be redesigned for universal (barrier-free) access. One of the three tram stations in Darmstadt was about to be redesigned and the results of the safety assessment contributed to the planning to avoid future risks. The other two tram stations served facilities with a potentially higher degree of risks such as schools and a football (soccer) stadium.
On behalf of KfW bank and the Vietnamese Railways (VNR), SIGNON became involved in the modernization project of operations control centers (OCC) in Vietnam.
Following a feasibility study and propagation measurements for GSM throughout the rail network, the existing processes at VNR were subjected to a thorough analysis. Processes and responsibilities were examined and adjusted to the requirements of automated operations. Armed with these data, our experts created a new concept for the structure and functionalities of the new operating control centers and then drafted the tender documents for the OCCs. And SIGNON continued at the disposal of the customer: In addition to the support during the contract phase and implementation, SIGNON was also responsible for the training on site of local staff and was able to assist VNR with its expertise and consulting know-how until the successful start of operations.
SIGNON was responsible for the planning of energy supply and contact lines of the new Brenner base tunnel.
The tunnel comprises two single-track tubes, each 55 km long, a 2x25 kV AC traction power system and 5 railway substations. SIGNON was responsible for the electrification and the contact line equipment as well as for the earthing and bonding system. Tasked with planning for approval of the rail power and contact line concepts, our experts worked side by side with BBT SE from 2006 to 2014. We were responsible for the SCADA system with RTU as well as cabling, 50 Hz auxiliary systems and the earthing and equipotential bonding system design. Our services for this tunnel project are further included RAM and safety studies as well as network simulations for the rail power supply.
Bombardier Italy has been commissioned to modernize the "Irmak Karabük Zonguldak Railway Line" in Turkey.
Along with the modernization it is necessary to integrate neighboring signal boxes. Thanks to its extensive know-how in relay technology SIGNON was able to take on this task and to support Bombardier in the planning of the interfaces with the signal boxes. SIGNON is also supporting Bombardier in the design of the new electronic signal boxes in accordance with existing TCDD regulations, and analyzed local requirements resulting from the circuitry of the old relay signal boxs systems. Bombardier then used the results as basis for the design of the new electronic signal boxes. Within the scope of work the parties inspected the line to analyze the existing level crossings, which resulted into recommendations for action, on the basis of which Bombardier developed further actions for the level crossings.
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.
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.
For the Hungarian railways specified for ETCS deployment, customer Siemens requires the validation of the position and content for ETCS balises.
Specifically, on the lines in the Szekesfehervar region, i.e. Monor - Szajol and Szajol- Gyoma. SIGNON uses the tools SAT.engine and SAT.valid to provide the validation services requested:
When the project is checked, these data allow to confirm to which degree the planned locations for balise groups are consistent with the measured data. Further reference elements used are the signal and points measurement data. Checking of the balise programming establishes for all balises that are passed, to which degree the telegrams read are consistent with the project planning as to ID (NID_C, NID_BG) and position in the group (N_PIG). All validation results are clearly documented in comprehensive test reports.
The Turkish state railway TCDD is planning the countrywide implementation of ETCS into their route network.
Commissioned by TCCD, SIGNON evaluated the ETCS Level 1 solution for the Eskişehir — Esenkent line and prepared a specification for future ETCS Level 1 projects. The project is structured in 4 phases:
The objective of the implementation of the AWAP project (automated warnings) at SBB was to follow-up an innovative development for the technical support of safety and warning procedures in the track area and thereby enhance the protection of track maintenance crews.
The project aimed at developing and implementing a new, comprehensive strategy for securing jobs, enhancing safety conditions when working in the track area, and reducing cost. In connection with the project, SIGNON helped SBB create the technical concept, define processes and procedures and integrate them into the peripheral systems. The warning system itself is based on information derived from the safety layer and transmitted via radio to the job site or warning device. In addition to the actual warning output, the system ensures a fully integrated planning process for jobs sites in the SBB environment. In further process phases, SBB will focus on both regulatory and technical developments and their network-wide introduction at SBB.
SIGNON was commissioned to determine the track-related distances between signaling equipment in Australia (North Line between Berowra station and Wyong station and Cronulla Line between Sutherland Station and Cronulla Station).
To this end, we applied our specially developed SAT.engine tool, which is installed on a traction unit and works up to 100 km/h. Based on GPS/GNSS measurements with synchronized video recording, the SAT.engine tool affords a cost effective and efficient inventory of the track infrastructure and its signaling equipment. Customers can use the standardized datasets hereby produced flexibly in subsequent planning processes. Customer Alstom received the distance and gradient data for about 180 track-km of the lines mentioned for further processing.
Services carried out for customer SIEMENS:
a) Acquisition of track-related infrastructure data using SIGNON's SAT.engine tool for S-Bane - suburban rail network in Copenhagen
b) Measurements runs on all specified tracks of the network (a total of about 400 track-km)
c) Measurement and evaluation of about 3,850 relevant track elements or their locations and determination of track gradients.
As a result, the customer received element lists stating the distances between signaling equipment, gradients, as well as complete video records of the routes traveled (element datasets, gradient datasets and video datasets). During 2010 to 2015 we carried out 4 measurement campaigns lasting approx. 3 months each.
Libyan Railway (LR) proposed the construction of a new double-track high-speed line along the Mediterranean coast between the Tunisian and Egyptian borders.
SIGNON was tasked with the planning of the technical equipment for track section Ras Ajdir - Sirt (630 km) and Sirt - Benghazi (550 km). The preliminary planning was drafted based on existing concepts, which were also from SIGNON, and coordinated with the customer. The concepts were based on European specifications and, in addition to electronic signal boxes (ESTW), also included the European ETCS Level 2, operation control centers, telecommunications systems and transmission equipment as well as GSM-R telecommunication systems, passenger information systems including SCADA, CCTV and fire detection and intrusion alarm systems. Planning also included hot box/brake detection systems (HOA/FBOA) and rail power supply. Subsequently, we drafted the tender documents for the preferred option and prepared the bill of quantities. The tender was published by the Libyan government in May 2009 and the contract was awarded to ANSALDO STS (Genoa).
For this study, SIGNON was tasked to integrate the requirements of the customer, given that general requirements and demands applied to the traffic forecasts made. The focus of this work was the operational concept. The signaling section included the comparison of several train control systems as result of which the introduction of ETCS Level 2 was proposed. For the telecommunications section SIGNON was tasked to propose station equipment and open track equipment. Such equipment included all necessary internal and external communications systems, including mobile telephony and electronic ticketing equipment. In connection with the proposed operational concept SIGNON also developed the structure for a future CTC (centralized traffic control) including the corresponding spatial concept. Another section considered in the study was the energy supply for signaling and telecommunications systems. Based on the equipment proposed in the study, we prepared the respective cost estimates.
In order to meet the future demands of rail travel set forth in the transport policy objectives of the canton, it was necessary to create a line from Altstetten - Central Terminal - Oerlikon, which runs through a tunnel.
The "Cross-City Line" project was divided into four sections. An engineering partnership - IG Züri BT - was formed to implement the rail technology project. SIGNON was a vital member of this partnership and in charge of the planning services for cabling and electrical systems. However, our experts also contributed with their know-how to the contact line and traction power planning as well as to the signaling and safety systems planning. Together, all partners completed this project very successfully.
Between 2005 and 2010 and on behalf of Thales, SIGNON drafted the detailed implementation planning for signaling systems, level crossings and underground cabling for a 365 km long route with 32 stations and 83 railway crossings.
The project called for the modernization of the East-West corridor line between Ventspils-Jelgava (a) -Krustpils and Daugavpils-Indra-national border, including the replacement of the existing signal boxes by modern electronic signal boxes. The necessary planning was done together by the experts from SIGNON and Thales. Challenges included operating rules for the signal box and signaling systems only available in Russian as well as the implementation of LdZ's requirements for the signal boxes. Thanks to the utilization of a video-based recording system it was not only possible to reduce business travel for on-site inspections but also provide Latvian Railways with accurate inventory documentation of the present system status.
The Deutsche Einheit Schiene Nr. 8 (VDE 8) project is one of the largest rail infrastructure projects in Germany. It was ratified by the Federal Government back in 1991, in order to improve the transport links between East and West, and North and South.
With a total length of about 500 km, the line is the core element of the future high-speed link from Berlin to Munich. Since 2012, SIGNON has been involved, in several projects for various customers, in the planning and implementation of track sections 8.1 ABS/NBS Nürnberg – Ebensfeld – Erfurt und 8.2 NBS Erfurt – Halle/Leipzig. We have delivered cross-system planning services for telecommunications systems, 50Hz equipment and control and safety systems for various performance phases. For the first time SIGNON has also delivered planning services for ETCS L2oS (without signaling), based on which the new European Train Control System in Germany has been officially launched.
SIGNON participated in the drafting of SRO's running regulations and also examined operational scenarios to enhance performance on the Dammam – Riyadh route.
Since 2006, SIGNON has been working with SIEMENS and THALES in Saudi Arabia. In 2009 SIGNON was already tasked with the planning (PT1) for the signaling systems for 51 stations and operating control centers along the North-South-Railway-Line (NSR) of the Saudi Railways (SAR). First, our experts drafted a planning guideline, which was then used as basis for all subsequent planning activities. In addition, SIGNON contributed significantly to ETCS Level 1 and 2 planning and provided technical support.
Within the scope of the project, the outdated and labor intensive signaling system on route 2271, between OCCs Duisburg-Hamborn and Spellen, was replaced by new electronic signal box technology, and two signal computer were linked to the ESTW-Z Oberhausen West.
In addition to the modernization of the signaling technology, new points heating systems as well as new or adapted telecommunications systems were implemented. As general planner for DB Netz AG, SIGNON is responsible for the provision of the planning services for performance phases 1 to 7 as per HOAI, i.e. control and safety systems, telecommunications systems, electrical systems (50 Hz), underground cabling as well as outdoor installations/access to ESTW modules and points heating systems.
Between 2007 and 2014, SIGNON was responsible under this project for the review of concept planning regarding signaling, telecommunications, electrical equipment and underground cabling.
This was followed by the implementation planning for signaling technology in various construction stages for the conversion of the neighboring operating control centers of the new airport railway station, using conventional signaling technology; The implementation planning for signaling technology for the new ESTW type Simis D intended to control the long-distance train areas and type Simis C to control de suburban train areas; Finally, the preparation of the tender documents in several procurement packages covering all sections of the technical equipment.
Due to a fire which destroyed the relay room of signal box Wolmirstedt in 2011, the control and safety system at Wolmirstedt station stopped working.
The existing old system could not be put back into operation at reasonable cost and, therefore, had to be replaced as quickly as possible by a new ESTW-A. The scope of work for SIGNON included the planning services for LST (control and safety technology) (including level crossings and ZN/ZL), telecommunications systems, electrical engineering, underground cabling as well as the outdoor installations for the new signal box (access roads, parking, fresh and waste water connections) and implementation of special solutions (e.g. signals on platforms). The project was completed in a record time of just over six months (from project definition to commissioning of the new technology).
The SRO network links the cities of Dammam - Hofuf - Riyadh in Saudi Arabia.
In its capacity as planner, SIGNON drafted the implementation planning for the signaling systems of the double-track expansion of line 1 between Hofuf and Riyadh build by SRO. SIGNON has been working as planner in several SRO projects since 2006. Close cooperation with the experts who take the necessary distance measurements for ETCS using SIGNON's SAT.engine tool, also contributed, among other things, to further work in underground cabling planning. Based on many years of experience in the fields of signaling, telecommunications and operations, SIGNON's experts were also able to provide technical and operational support to the customer.
SIGNON has provided a variety of planning services for Magdeburg railway junction since 1998. Expansion level 1 called for a new ESTW at Magdeburg railway junction with 3 sub-master stations and a total of 8 ESTW-A signal boxes, electrotechnical systems and points heating systems.
To this end, our planning engineers drafted the concept and implementation planning for the control and safety systems (LST PT1) and the tender documents. Expansion level 2 called for the modification of the track layout at Magdeburg central station and for several adjustments in the neighboring OCCs with regard to control and safety systems, telecommunications systems and EEA (DB Netz, DB Station und Service, DB Energie) for performance stages 2, 3, 4 and 6. Here, too, we provided all implementation planning at PT1 level.
Together with Ramböll, SIGNON has provided extensive consulting services for the route Oslo-Ski. In addition, our experts have supported the customer in the ETCS planning for this route.
The objective was to make this route an ETCS pilot. Within the scope of the project, we drafted concept and designs, which were used as basis for further discussions with JBV. Other content for this project included the drafting of the technical and operational requirement specifications for ETCS, cost estimates and risk assessments. The work with partner Ramböll was successfully concluded in 2012. Based on the planning the route was later on equipped accordingly and successfully commissioned.
In the course of the complete replacement of the existing control and safety technology (control systems, signal boxes and train protection) JBV decided in 2013 to deploy ERTMS in Norway. The "Nationwide ERTMS Implementation" project is aimed at the network-wide replacement of the existing and mostly relay-based signaling technology.
The new train control and protection system will be ETCS Level 2. To this end, the first step was to develop a nationwide roll-out plan. The overall project, scheduled to be completed by 2030, calls for the systematic use of technical consultants.
Together with Ramböll, SIGNON has been in charge of technical support for JBV since the start of the project. SIGNON's main fields of activity include TMS (Traffic Management System), ETCS trackside equipment and work on system integration.
The renewal of the control and safety technology in the OCCs of Bf Aachen-Rothe Erde, Bf Aachen Hbf and Bf Aachen Süd, also included a new ESTW-A at Bf Aachen Hbf and the connection to ESTW-UZ Düren.
Further changes included new locally operated electric points (EOW) at Bf Aachen Hbf, changes in the track layout at Bf Aachen Hbf, new and adapted signal brackets as well as special constructions for the positioning and mounting of signals. Between 2005-2012, within the scope of the project, the Belgian train control system Crocodile was adjusted and upgraded, the signaling technology for the voltage change-over system (15 kV AC - 3 kV DC) at Bf Aachen Hbf upgraded, the neighboring OCCs Bf Stollberg and Bf Aachen West adapted, the block system on the cross-border route from and to Belgium adapted and the contact line (15kV AC) / local control adapted or expanded. Points heating systems, the cable routing system and the track field lighting are completely new and 50 Hz power supply were expanded.

This is a follow-up project within the implementation stage of ETCS Level 2 in Austria, where SIGNON contributes to the planning of the Brenner route (Kufstein – Brenner) and of the new route Vienna – St. Pölten.
Based on the equipment data acquired from ÖBB's first ETCS level 2, for which we defined the technical bases, operations and supplied the preliminary planning, there are three track areas around Hbf Vienna which are now object of our ongoing project support. As part of the project support SIGNON will assist ÖBB in all technical questions and problems regarding the ETCS infrastructure equipment. From the drafting of the tender documents to monitoring of the manufacturing company, from development to installation and the activities in the approval and acceptance phase, we will process all infrastructure-related issues in accordance with the current state-of-the-art and prepare them for our customer. The SAT.engine tools is used to measure track sections, while the SAT.valid tool is used to check the balises.
An example of our leading expertise in the field of ETCS is our collaboration, in all project phases up to commissioning in 2012, in the practical implementation of ETCS Level 2 in Austria on the Brenner route (Kufstein – Brenner) and on the new route Vienna – St. Pölten.
For the equipment of ÖBB's first two ETCS level 2 routes, we defined the technical bases, operations and supplied the preliminary planning. Afterwards, we drafted a specification, which was used to prepare and follow-up the invitation to tender. Subsequently, we followed up the manufacturer's work regarding development and installation as well as the activities required for the approval and acceptance phases. In addition, the ETCS-relevant infrastructure elements were measured in certain track sections and evaluated in terms of distances and gradients using the SAT.engine tool.
Upgrade and expansion of the infrastructure of Bf Duisburg-Wedau included a new marshalling yard with two fans of sidings, each with 6 new tracks, as well as a new garage siding with 5 tracks for locomotives.
