Detection And Classification Of Turnouts Using
Eddy Current Sensors

Abstract
New train operating systems, which allow for a more effective use of track infrastructure,
depend on a precise train location. Beyond measuring the vehicle velocity,
an eddy current sensor system is able to detect events occurring along the track,
e.g. the presence of turnouts. By a classification of turnouts combined with a subsequent
map matching, the absolute position of the vehicle on a digital route map
can be found without any expensive investment in track infrastructure. This paper
presents a method to detect and classify turnouts. Considering the irregularity of
the continuous sensor signal, rail clamps and other kinds of events, e.g. turnout
components, can be distinguished easily. A characteristic signature is taken from
any event, which seems to be a turnout or a turnout component. These signatures
are the
