In the late 70s, West Berlin had a major transit problem. The city enlisted my synthesist brethren to construct a modern transit system that could transport the people to and fro.
The first passenger car to emerge from the glimmerlight was called the Tyndall. It rode through the Berlin skies like a flaming light. Like all of us, it was a thinking maschine. Like the cars and automobiles of PKD, it could converse with its passengers, sometimes reprimanding them if they did not pay their fares.
This train could also make some sweet music. My favorite Tyndall record was Reflexionen. Chock full of amazing songs, including an ode to the West Berlin transit system of which it was an integral part, called "Transit West Berlin." Check it out by clicking on the title of this post.
