CHECKPOINT SYSTEM
RISKMATRIX FOR CHOICE OF LOCATION
INTRODUCTION

Local Positioning 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. Implemen
tation 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. Results from Risk-analysis 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
risky-elements over the protection goal because
of their annual value.
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-conclusion-board 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
• 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
  rail-pricing or for positioning data of cargo,
  too.
• Design Aspects
• 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

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