I would like to add some detail on railway and tram lines in my area and have been searching for a tag for "rail movement joints" / "railway expansion devices" (I found these terms online, the German term is "Auszugvorrichtung").

How should we tag these features in OSM? railway=movement_joint? railway=expension_device?

Which object type should be used? From a map perspective, they might be "point" features, marking the point where the tracks are cut.

(German below) Dear railway mappers, I would like to add some detail on railway and tram lines in my area and have been searching for a tag for "rail movement joints" / "railway expansion devices" (I found these terms online, the German term is "Auszugvorrichtung"). The feature in question is a device often found on railways at bridges or long straight tracks. It allows the tracks (and the bridge undereath) to expand or shrink in length (as a result of temperature change) without damage. This seems to be the matching DIN EN: http://www.fsf.din.de/cmd?level=tpl-art-detailansicht&committeeid=547... ...and BS EN: http://shop.bsigroup.com/ProductDetail/?pid=000000000030214647 How should we tag these features in OSM? railway=movement_joint? railway=expension_device?

Ich habe nach einem tag für Auszugvorrichtungen (Konstruktionen zur Aufnahme der Wärmedehnung der Schienen an Brücken oder langen Geraden) gesucht, weil ich ein paar Details zu Streckenabschnitten nachtragen wollte, mit denen ich zu tun hatte. Wie sollen wir so etwas taggen? Im Netz habe ich die oben aufgeführten Übersetzungen gefunden, die zu den genannten tags führen könnten. Weiterhin müsste man sich gedanken machen, ob man die Stelle der Trennung als Punkt taggen will (generalisiert) oder die ganze Konstruktion von Schweißnaht zu Schweißnaht als Linie erfassen möchte. letzteres ist mit unserer erreichbaren Positionsgenauigkeit natürlich nicht ganz so einfach.

The source I was citing is 'Modern Railway Track' by Coenraad Esveld, second edition. The book is regarded as academic handbook on railway engineering and was written by a cooperation of Dutch, German, British, Austrian, Belgian, French, Japanese, Korean and UIC engineers. I think that, despite the absence of Russian and American engineers, it covers the global view on railway engineering very nicely. Regarding the specific tastes of expansion systems we can consider: • fishplated joints in non-continuous track • joints and expansion devices • bridge transition structures Additional there are two more joints without > Op 22 jun. 2015 om 23:42 heeft Michael Kümmling <michael(a)kuemmling.eu&gt; het volgende geschreven: > > Hello, > > Translation of railway terms is difficult, as wording differs almost > completely between British English and American English.

I still have a lot of data available and even aquired new data on the electrical catenary systems. same here, my first exams are now over too. Sorry, that our discussions almost stopped in the last weeks, but it seems that you were busy, too... I hope that we can finally make some progress in the next weeks and months. > In order to inform you on the Dutch situation and to discuss how to implement it's data, I propose to arrange an online meeting.

Thank you in advance. Good idea. I am on travel until 2nd August. When I am back at home, we can arrange a discussion.
