Abstract [en]

The European standard EN 50128 "Railway applications -

Communication, signalling and processing systems - Software for

railway control and protection systems" is one of the European

standards for European Railway systems. It is intended for

software aspects, specifying procedures and technical requirements

for the development of programmable Electronic systems, which are

used in railway control and protection applications. Since 2017-

04-25 the original version EN 50128:2001 has been replaced by the

updated new version EN 50128:2011. The update is quite extensive

and will effect many parts of the existing Railway systems. The

aim of this study is to investigate the effect of the EN 50128

update.

The work for this study includes literature study, document

research and interview with the relevant supplies and experts.

Qualitative and quantitative methods have been used in the study

to reach the possible best results.

The effects due to the EN 50128 update have been extensively

investigated. The following issues have been addressed:

- How can the update of the standard EN 50128 be done smoothly by

the companies?

- How much money have they spent to update their process to follow

the 2011 version?

- What parts of the process have been the most extensive and

expensive to change due to the standard update?

The results of the work are useful for an organized and

professional assessor to help and support the companies dealing

with this complex software, in order for them to be prepared for

the upcoming standard update as well as possible. If the affected

companies have been proactive in their own development of their

methods/techniques, the 2011 version of the standard will not be a

major work to follow for their process. A standard is a guideline

and a support in the way to a safer system.
