Stable Concept, flexible System
Reliable and precise: An ever-increasing proportion of operators and system integrators are being won over to axle counters. Their primary use is for track vacancy detection, for which specific criteria apply depending on the market. The Frauscher Advanced Counter FAdC accordingly offers great flexibility here.
The FAdC makes highly market-specific adaptations possible as well as higher-level solutions. Frauscher has had a presence and a base in India since 2013, and the Indian railway industry needed a marketspecific adaptation. The team on the ground in India has meanwhile expanded to around a hundred people, and they are familiar with all the specific detail of that market. One element of this is dealing with what are known as push trolleys.
To this day the use of these manually-operated rail vehicles is widespread in India. They are mainly used for inspecting infrastructure, track condition or signalling systems. The challenge: push trolleys can be placed on the track at any point. If this is done on a section on which track clear indication is performed using axle counters, when the trolley crosses the next wheel sensor the result will be a count error. If push trolleys are only used on sections that are not being used by trains at the time, then this scenario can be rectified with the CHC function. However, especially on long sections – for instance between two stations – a trolley may be placed on the track in an occupied section. If it crosses a relevant wheel sensor it can be detected and cause a fault.
