Demonstration project of lifetime engineering in AUSTRIA :
CHECKPOINT
SYSTEM
NETWORKING OF
CHECKPOINTS
INTRODUCTION
Apart from an increase in safety and quality, the introduction of the new
OeBB (Austrian Federal Railways) management operation system has to
result in a reduction of operational costs. This goal can only be achieved, if
the personnel is concentrated on a few locations and the traditional train
supervision is replaced by a technical solution, the so-called Checkpoints.
Checkpoints can be defined as track-side locations where the trains are
examined to detect any deviation from normal condition. This check is
executed by sensor components which are passed by passenger and/or
freight trains with the locally authorized speed. The data collected is
considered as an important source for subsequent activities.
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
Hot bearings, hot and stuck brakes
Displaced cargo, open doors,
silhouette violations
CHECKPOINT
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.
Network structure
The checkpoint center is connected
to all checkpoints. Major features of
centralized networked structure:
Trend analysis
Logging for further
improvements
Only checkpoint center has to be
protected against failures
Centralized failure management
Advantages of a networked
Checkpoint system
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”

Train gauge monitoring system (ASE
Industry)
A stand alone checkpoint provides
only a snapshot like evaluation of the
train. Networking checkpoints is
useful for continuous train monitoring.
Remote maintenance and
configuration
Relations between different data
sets
Design Aspects
Dynamic scale (Schenck Process)
Basic reasons
Controlsystem
Interlockingsystem
Because of trend analysis, it is
possible to detect slow condition
changes on the train. This implies:
Risk reduction of occurrence of
fault states between checkpoints
Early generation of alarms
without impairment of the current
traffic
Optimization of wagon
maintenance intervals
Data of one checkpoint can be used
for other less equipped or partly
defect checkpoints (“virtual sensors”).

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.
