smart HSG-city
smart HSG-city is a groundbreaking solution for urban rail networks that enhances track availability, significantly extends rail service life and reduces noise emissions from rail traffic by up to 10 dB(A).
Why do light rail tracks need preventive rail grinding?
Now in use in more than 40 countries on four continents, the compact grinding machine is an indispensable solution for operators of light rail and tram networks in order to meet the increasing challenges in an efficient manner. Urbanization is a global trend. To absorb the growing number of passengers on local public transportation, operators often shorten intervals and extend timetables as a first step. As infrastructure strain increases, both the scope and frequency of required inspection and maintenance measures rise – now within tighter time windows. All of this adds to the complexity of maintenance.
Solution: Digitally enabled, targeted maintenance – integrated into the timetable
In order to keep the route network efficient – taking into account the given budgetary constraints – it is advisable to differentiate rail processing according to location and type. The digital networking of rail diagnostics and processing gives the smart HSG-city a new dimension in customer use: instead of the "watering can” approach, in which complete track sections are ground uniformly, often resulting in unnecessary treatment of some areas and insufficient attention to others, Vossloh’s Smart Maintenance delivers a holistic concept for condition-based rail maintenance and full transparency: from inspection and monitoring to clearly derived maintenance scenarios, including cost analysis, through to the corresponding maintenance measures. At the same time, the software-supported maintenance approach enables plant managers to use their budgets more efficiently and retrospectively assess the effectiveness of their actions.
For demand-oriented rail processing, several fully integrated laser triangulation sensors on the compact grinding machine record the rail condition and check the track geometry. Thanks to the High Speed Grinding technology both condition monitoring and grinding can be carried out at a variable speed of 8 to 60 km/h in the timetable without a break.
How well do you know your network? Let's talk about how we can adapt our technology to the specific needs of your city. Implement the smart HSG-city technology and transform your urban transportation system into a role model for modern efficiency, sustainability and high customer satisfaction.
If the removal is moderate, the smart HSG-city can carry it out immediately. In high-stress track sections, the compact VTM-compact milling machine delivers quiet, precisely reprofiled rails – removing up to 2 mm in a single pass.
With 24 whetstones, 30 km can be processed non-stop, while carried replacement stones can be swapped out within minutes. The compact machine can also be used bi-directionally and can be towed by different vehicles, such as a two-way Unimog or a tram. Grinding speed is adapted accordingly – ranging from 8 to 60 km/h.
