Not so easy to translate
The more sub-words there are the harder it is to distill down to exactly what they mean, but:

Donau  dampf  schiffahrts  elektrizitäten  haupt  betriebswerk  bau  unter  beamten  gesellschaft
-----  -----  -----------  --------------  -----  ------------  ---  -----  -------  ------------
  |      |        |              |           |         |         |     |       |          |
Danube steam   boating       eletrical     main      depot     build  sub   official   society

Or, the association for junior officials of the main electrical servicing depot for steam ships on the Danube. That's a famous contender for longet german word.

Mine was:

Bezirks  verordneten  versammlungen  wahl
-------  -----------  -------------  -----
   |          |             |          |
Borough   delegate     assemblies    vote

Parish council elections, which I'm entitled to vote in.

EDIT: Oh. and Rechtschriebreform is Orthographyreform, or the spelling changes they brought in a decade or so ago.

Thanks. Funnily enough
I remember my fellow pupils who were studying German quoting an example given by their teacher - something like a steam powered mechanical shovel? I guess the need for new terms around the time of the industrial revolution has something to do with it.
