INTRODUCTION
The planned withdrawal of the station inspector from the field means an
drawback on the organizational and technical level for the system of the
railway. With the passage of a train the presence of the train-conclusionboard is examined, as well as apparently recognizable irregularities, as for
instance overheated axles. Due to the restructuring also checking of the
passing trains at the commercial stations is decreased, and a call for action
exists, since these functions must be taken over now by technical systems.
Functionality of Checkpoints
At the moment, several failure scenarios
in the railway system have been
identified:
Derailed wagons, broken axles or
bearings,
Flat spot, reweldings and cracks on
wheels
CHECKPOINT
Hot bearings, hot and stuck brakes
Displaced cargo, open doors,
silhouette violations
Fire, overweight, broken
pantographs
Numerous sensors are available.
Combining sensor data provides better
and more information about the status
of the train. Data can be used for railpricing or for positioning data of cargo,
too.
The system should follow the following
aspects:
The whole system is highly modularized.
Sensor independent representation of
data.
Data is merged to a global “Train-Model”

The local positioning of the sensor
technology takes place according to
the last retaining possibility before the
risky element, which is placed safely
with signal box effect on the assigned
mandatory-signal.
Implementation of Risk-matrix
Therefore a team was arranged
consisting of experts of the Austrian
Federal Railways from different
divisions, which should help in the
search for the risks in a railway
network. Elements were sorted into
groups of “infrastructure”, “course”
and “surrounding field”.

Design Aspects
Dynamic scale (Schenck Process)
Local Positioning
Controlsystem
A combined procedure to define the
protection goal and to derive priorities
for measures for risk reduction, is e.g.
to use a monetary protection goal on
an annual risk. Based on this idea,
ranges in the matrix can be identified,
which are over or under a protection
goal. So priorities for a expansion
strategy are given by sorting riskyelements over the protection goal
because of their annual value.

Checkpoint center stores,
analyzes, validates, logs,
forwards data and decides,
which influencing factors have
to be taken into account for
optimal processing.
Alternatives, to get detailed
train information from the
train operator or techniques
to get detailed information
about train configuration by
new Checkpoint sensors.
