Spurwechsel

This pretty much sums up the first couple of decades with cars. As always, it took quite some time to work out the kinks in the system. For example:

• How do you mark pedestrian crossings? (First attempt to do so was in 1926, when cars had been in Vienna for at least twenty years. In 1910 Vienna had about 4000 cars.)

• How many traffic signs should there be? (Drivers thought sixteen were far too many.)

• ...and so on...

The advertisement for the exhibition.

A "transformer chain". The chain is charged by turning the crank at the far left, and then proceeds to pump water to the top tank, which drives a generator, which powers the two spotlights on the little car, which illuminates the solar cell, which drives the car up the slope...

Government poster. "The anti-social has no consideration in street traffic." Fun fact: The word "anti-social" is the same word used by the Nazis to denote "enemies of the people"[a].

Government poster. "Even without him, show discipline!"

Railroad car. I don't think you'd even be allowed to let condemned men ride in a car like this anymore.
