Models of interlocking frames at the German Museum of Technology, Berlin

Deutsche Version dieses Postings

Two weeks ago, on a business trip to Berlin, I visited the German Museum of Technology ("Deutsches Technikmuseum") to take a view at one single display: One day before, I had found out that there is an exhibit of a few models of German interlocking frames from the 1880s, built by various signal companies for demonstration purposes. I will not explain their details here, but just show a few pictures.

Here is a view of the display case with its models, all of them scaled 1 to 5:

One can see the following five models—I also give links here to museum-digital, where one can see an additional picture of each model:
A sixth model of type "Rüppell/Büssing", which can be seen online here, is not shown in the display case.

Here are a few random pictures that I took (unfortunately, my SD card had a problem, so I lost some pictures I shot; maybe I'll go there another time to shoot more):

These are all my pictures of these models from some 125 years ago. In an upcoming posting, I will show a model of a mechanical frame that is much (much) younger—stay tuned!
