Öffentliche Verkehrsmittel habe ich gern!
(I like public transportation!)
I wish we would build much more of it in the USA. It's fascinating to watch how many trains stop at the Dueren Bahnhof PER HOUR! Remember, if you are happy taking public transportation, you don't need to buy, feed (fuel), repair, insure, clean, and store your own automobile; which, if you think about it, would be like your boss agreeing to give you a significant -- think WHOPPING -- raise.
Better yet, you wouldn't need to have a job at all. American kids often work to support their cars. [That, and of course to save for college. And how much tuition did Florian say he had to pay this semester at RWTH Aachen Universitaet? RIGHT: 500 EURO; about US$ 750. ]
Back to today's topic: Here's how the RR beds are built near our partner school. You might be as fascinated by this as I am.
I believe that it was from Flickr that I learned how amazingly strong the machine is at 4:20. It meshes the stones so tightly together that they become as strong as concrete -- while at the same time, the tracks remain fully accessible, should repairs be needed. etc.
--> Where in the USA might we put new train tracks in this manner ?
