Rhomberg’s James Allen highlights the


products and systems the


company will be showcasing at this year’s InnoTrans show.


resenting at InnoTrans this year, Rhomberg is aiming to showcase its technical innovations. These include: • A new slab track system called IVES • System RhoTAS G5 for installation and adjustment of different slab track types. • A new structure for transitions between slab track and ballast track sections.


Two further areas stand out in particular – access control & safety, and accurate surveying equipment.


Ian Knowles, Rhomberg Rail UK general manager explained: “Rhomberg has vast experience of working with slab track, as you can see from our stand.


“With slab track it is very costly to correct mistakes. Our systems are designed such that we get it right fi rst time, every time.”


Knowles went on to describe the issues faced by Rhomberg in the Brenner Tunnel works. “The project included a 34km section of twin-track tunnel with approximately 25 access points. With an excess of 3,000 workers on site at peak operations access control, plant and material co-ordination was recognised as signifi cant problem that needed a new approach to be adopted. Thus was born our ZOKA system.”


Access Control & Safety


ZOKA is a centrally controlled system, which on a zone-by-zone basis allows the monitoring and control of access (personnel, plant and material) via wi-fi tagging, and advanced communication to and from workers located in the tunnel. Additionally the system allows the control and monitoring of environmental systems as well alarms and evacuation.


All the information from the ‘ZOKA’ control and monitoring system are brought together in the control centre which is constantly monitored. ‘System Zones’ are added progressively as work proceeds along the tunnel. The system need not be limited to the construction site, but can be extended to include compound and storage areas, offi ces and workshops. As the system is wi-fi based, there is not a requirement for the employee to physically ‘sign’ in or out.


The system can be programmed with information

qualifi cations and will not allow access to those whose certifi cation has lapsed. The highlighting of excess working is also possible.


Site communications play a key role in the safe management of construction sites. They ensure that proper connections with the outside world are maintained and information can be exchanged effi ciently on-site.


Rhomberg has developed special communications distribution cabinets, which – when positioned at regular intervals and fi tted with the appropriate communications solutions – can provide a reliable network for safety and security.


Surveying


The innovative Hergie track surveying system was developed as part of the high-speed Cologne-Frankfurt (Germany) rail project by Rhomberg Rail.


This online measuring system for the adjustment and documentation of track condition, compromises of tachymeter- controlled track surveying trolley, which optimally measures track position, cant, gauge and rail inclination. The measured data are compared ‘online’ with the pre-specifi ed values for height, position and alignment. Deviations to these values are shown in real-time on the user’s monitor. This means that they can be immediately and accurately detected to be rectifi ed on the spot.


The basic pre-requirements in describing track geometry using coordinates are: • An accurate and stable reference-point network


Having gained experience in all areas of railway engineering means, our expertise is in demand all over the world. Our strengths include providing complete solutions tailored to meet the customer’s specifi c requirements. Our range of services is as broad as it is long. Starting with design, project management and planning through to maintenance, from provision of the required machine resources to technical site equipment, we can take on all types of railway and track construction work. As a customer of Rhomberg, you will fi nd we have the expertise and skills that perfectly match your exact requirements.

• Accurate measurements of coordinates at individual points


Individual track alignment points are measured using a precision tachymeter (direction angle ≥ 0.3 mgon). The relative accuracy between two reference points at a distance of approximately 60m is subsequently below 0.5mm. As Knowles proudly points out: “All this functionality is available in one piece of equipment, and it fi ts in the back of your car!”
