Dutch mechanical interlocking: a German-Austrian-British mix

[hmmueller]

I have just completed a first posting that explains the, in my opinion, quite interesting mechanical frames that were present in the Netherlands in the last century. I immediately recognized the interlocking frames on the "Zud-Limburgse Stoomtrein-Maatschappij" museum steam railway as the Austrian (Siemens) type 3414 - but further study and photos showed more and more British elements in the "interlocking culture" of that country, which I hope to unveil a little in this and a few following blog postings:

Interlocking frames in the Netherlands - a mix of British, German and Austrian practices!

I hope this is interesting for some readers curious about interlocking all over the world!

Best regards

Most interesting. Thank you for taking the time to prepare and publish these. I have only had time for a quick look at your pages but I will study them in detail in due course.

Please keep up the postings.

Not sure about frames but Dutch relay interlockings were largely done with British relays and circuit principles. Their train describer specification was a slightly modified version of the BR one which I helped to write at Carlow St. The Amsterdam Centraal panel scheme (now superseded) was American.
