This system makes the track more homogeneous and stable due to the even weight distribution.

With ballasted track, the ability to install the equipment on top of a concrete sleeper avoids the need for a hollow steel sleeper. Instead the concrete can be poured continuously and the switch machine is subsequently installed on top of the concrete surface. There is no need to provide cut outs in the concrete slab, which reduces the complexity of civil works thereby cutting costs. Each point machine is characterised by its modular and compact design, which offers increased flexibility when mounting the units in the track and in the centre of the gauge.Ī particular feature is the ability to mount the equipment on top of concrete slab track or concrete sleepers.

To meet these challenges, Voestalpine Signaling developed a series of point setting systems called Unistar HR, CSV 24 and CSV 34. Furthermore, environmental factors such as rain, snow or dust increase wear and thereby the maintenance effort. Wide variations in temperature cause switch points to expand or contract, which means that a periodic summer and winter adjustment is normally inevitable for the continuing reliability of the system. Moreover, turnout systems have to be reliable even in extreme environmental conditions. A reliable diagnostic system is also needed to monitor heavily-used systems between inspection cycles and to detect irregularities at an early stage which will prevent failures. Indeed their availability demands are extremely high, since failures cause immediate delays to train services.Ī new generation of turnout is therefore required which will reduce the demand for maintenance and increase inspection cycles. Point machines and locking devices in particular must be able to meet these demands as they represent a complex link between the signalling and the track. Providing reliable infrastructure with low demand for maintenance is therefore crucial for system availability and reliability.
This often means reducing headways to provide a more frequent service, which in turn reduces the time available for infrastructure inspections and maintenance.
RAILWAYS around the world are responding to growing demand for their services by increasing capacity.
