About me

rainer portraitI have been professionally involved with mass transit vehicles for about 40 years. As a project engineer, I mainly have been responsible for the conventional electric technology of many metro vehicles worldwide from various aspects. In addition, I am familiar with multiple units, trams, and buses. I have more than 10 years’ work experience with both vehicle operator and vehicle manufacturer.

From the vehicle point of view, I was able to gain extensive experience in connection with vital train systems, including with driverless and unattended operation (GoA4*). I was involved mainly in the design of conventional electrical safety circuits (up to SIL4) for many vehicles.

Since January 2020, I have been registered consultant, using my extensive work and technical experience to work with and support the development of smaller-scaled projects. For larger-scaled projects, I am a subcontractor in cooperation with ESE GmbH in Braunschweig (www.ese.de).

I am happy and ready to advise and support you in the creation of your electrical engineering concepts for the procurement of new vehicles and for modernisations, e.g., for the retrofitting of CBTC systems.

In addition, I provide support for the creation of documentation and presentations, as well as the creation of drafts for functional electrical circuit diagrams.

* - according to IEC 62290 Grade of Automation level 4, driverless unattended train operation.
