Tools and Methods for risk assessment
During the CSM dissemination workshops, questions have been asked about
when to use which risk assessment tools and where could more information
on this topic be found.
Some of the European railway actors have requested further support and
more detailed training on how the risk management and risk assessment
process described in the CSM Regulation can be applied. For some part of
them, the risk management and assessment concepts, as well as the respective
terminology of a risk based approach seem to be new. Sometimes, even if the
whole concepts are not new for them in theory, they confirm to be rather
inexperienced in their practical implementation. It has been reported that it
is often hard to find literature on these topics available in the own language
and this implies an additional diculty for the concerned actors.
Therefore, in order to assist them, the European Railway Agency has
decided to elaborate with the support of a subcontractor a training material
on the risk management and risk assessment techniques and tools.
For this purpose, a tender for a study has been launched in April 2010.
The work on the study has started in August 2010. The estimated date for
the completion of the activities lays in February 2011.
The aimed training material shall be supported by an analysis of advan-
tages and disadvantages of the methods and tools used in the different steps
of the CSM process. The risk management and risk assessment terminology,
the different techniques, tools and methods that might be needed to demon-
strate the compliance with the CSM Regulation, will have to be explained.
Their use shall be illustrated with instructive examples of risk assessment,
which are taken from different spheres of the work in the railway sector (con-
struction of new lines, changes of existing lines, introduction of new and/or
modified technical systems, operational changes, etc.).
The developed materials are going to be made available on the web page of
ERA. Their exact dissemination modes are going to be proposed and defined
in the scope of the work on their development.

Coordination between ERA and CENELEC
Currently, the CENELEC CLC TC9X Working Group 14 (WG 14) for safety-
related standards is working on a combined revision of the following stan-
dards:
- EN 50126:1999 [4], which specifies the Reliability, Availability, Maintain-
ability and Safety (RAMS) process for the railway system;
- EN 50128:2001 [5], which concentrates on the software in the signalling;
- EN 50129:2003 [6], concerning the safety relevant electronic signalling
systems;
- EN 50155:2001 [7], which is about the electronic equipment used on
rolling stock and does not have any special safety or software focus.
