Schlüsselschalter vs. Stellwerk
by Björn Mahrt 20 Dec '20

20 Dec '20

Moin, da es doch schon einige Bedienstellen/Fahrwegstelltafeln etc. für EOWs in der Datenbank gibt, stellt sich mir die Frage, wo da die Grenze zwischen Schlüsselschaltern und Stellwerken ist. Ein einzelner Schlagschalter an einer einzelnen EOW ist meist sicherlich noch eher ein "Schlüsselschalter"/key_switch. Was ist eure Meinung dazu? Viele Grüße Björn

The Map and the website.
by Natfoot 25 Nov '20

25 Nov '20

Hello to the group, If I wanted to contribute to the website map and design, how do I move forward? I had a hard time deciding from the wiki how to proceed. I did find https://github.com/OpenRailwayMap/OpenRailwayMap this by selecting the authors list and found the fork and pull methods. Shall I do such to make revision changes to the viewer? I would like to add an additional radial for railroad operator or ownership and work through the way that looks on the site. Maybe color code owner/operators. I am asking to see what has changed, as some things have not been updated in a few years. I don't want to step on anyone's toes as I move forward with my changes and future discussions. Eg. I want to step out on the right foot. Best Regards, Nat P email: natfoot(a)gmail.com

Re: usage=main/branch in Germany vs. other countries?
by JJJ Wegdam 19 Oct '20

Hello, The German definition is different than what was internationally agreed upon in OSM. In my opinion German mappers should allow me to change the usage tags on German lines in accordance with the international definition. Does anyone disagree? Best regards, JJJWegdam Background the German definition for Hauptbahne "Rechtliche Grundlagen Deutschland Die Strecken werden entsprechend ihrer Bedeutung nach Hauptbahnen und Nebenbahnen unterschieden. Die Entscheidung darüber, welche Strecken Hauptbahnen und welche Nebenbahnen sind, treffen für die Eisenbahnen des Bundes das jeweilige Unternehmen, für Eisenbahnen, die nicht zum Netz der Eisenbahnen des Bundes gehören (nichtbundeseigene Eisenbahnen), die zuständige Landesbehörde." the definiton on the OpenRailwayMap tagging page "Main line, mostly double tracked and electrified. Use this tag on railways with high maximum speed and dense traffic. Railway crossings are mostly elevated. In North America, this can include single-tracked non-electrified line, especially over very long distances." "Branch lines, which are mostly single tracked, not electrified and with lower maximum speed. Railway crossings are mostly at the same level as tracks."

In Germany, it is usually applied based on the legal status of a line as branch line or main line. This means, that sometimes single track lines with low speed and rather local relevance are tagged usage=main. What's your opinion? Regards, Micha

Railway Offline Style for OsmAnd
by Johannes Elstner 10 Oct '20

10 Oct '20

Hi there, I'd like to show you an offline map style I've created for the OsmAnd app, highlighting the railway infrastructure like in OpenRailwayMap. My motivation was to have a mobile offline railway map when I'm travelling around by train and I'm interested in the infrastructure outside. But as a railway engineer, I could even imagine using it for field work. You can find the download and installation instructions here: https://github.com/fuzzysolutions/OsmAndRailwayStyles The first release is just focusing on the line styling, so text labels and point style and labels are still ruled by the base style (Mapnik). Feel free to contribute feedback or improvements. Please note that there are some limitations, as the OsmAnd offline maps don't contain all the railway tags that would be interesting. Especially usage and highspeed are unfortunately missing. Greetings Johannes

Deutschlandkurve
by Philipp Klaus Krause 09 Oct '20

09 Oct '20

Guten Morgen. Gibt es ein Tag für die Deutschlandkurve (eine Kurve, bei der die äußeren Räder auf dem Spurkranz laufen, was besonders enge Radien ermöglicht, benannt nach dem bedeutendsten Hersteller dieser Kurven, der Maschinenfabrik Deutschland GmbH in Dortmund)? Philipp

usage=main/branch in Germany vs. other countries?

Hi, JJJWegdam noted, that the usage of the tag usage=main/branch differs between Geramany and other countries (see https://www.openstreetmap.org/changeset/20641783). In Germany, it is usually applied based on the legal status of a line as branch line or main line. This means, that sometimes single track lines with low speed and rather local relevance are tagged usage=main. What's your opinion? Regards, Micha

Improved tagging of two-sided signal signs
by Rolf Eike Beer 04 Sep '20

04 Sep '20

If one has two signals on the same pole, but facing different directions, the current tagging requires to place 2 nodes, one for each direction. I don't like it, for obvious reasons… I think I have something that we could work with, and want to her opinions on it. For the moment I would like to add a few restrictions to it: this only applies to signs, and only if the same sign type is used on both sides of the pole. Common examples are snowplow signals in Germany, where you have the "snowplow up" on one side and "snowplow down" on the other side of the pole. Another not that common example are Lf7 signs (speed limits). I can even think of Ne5 (stop inside station) to be shared, and here even if both directions have different length or not plates on them. The German mappers will hopefully get what I'm talking about. ;) So, here is what I propose: railway signal railway:signal:direction forward railway:signal:position right railway:signal:snowplow DE-ESO:ne7 railway:signal:snowplow:form sign railway:signal:snowplow:height normal railway:signal:snowplow:type up railway:signal:snowplow:type:backward down This has the usual tagging for the Ne7 snowplow signal. It also has one :backward, which would override the "type" for the sign mounted on the backside of the pole, and which for obvious reasons implicitely gets a railway:signal:direction=backward. I could think also of something like this: railway signal railway:signal:direction backward railway:signal:position left railway:signal:stop DE-ESO:ne5 railway:signal:stop:form sign railway:signal:stop:height dwarf railway:signal:stop:caption 100m railway:signal:stop:caption:backward 200m What cannot be done using this way of tagging is: -have a property on the forward-looking signal that the backward facing one does not have, i.e. one cannot "delete" the caption if the forward looking one has one, but the backward does not. One could simply invert the tagging in that case and make the backward signal the main one, and only add the property to the then-backside forward signal. One case that is not yet shown is when the signal is exactly the same for both forward and backward. I would suggest "overriding" the type in this case: railway signal railway:signal:direction backward railway:signal:position left railway:signal:stop DE-ESO:ne5 railway:signal:stop:backward DE-ESO:ne5 railway:signal:stop:form sign railway:signal:stop:height dwarf I'm unsure, maybe we should just always override the type in case of a backside signal, so one does not have to check all tags. What do you think? Eike

Kompliziert ist richtig! :) Aber was meinst Du mit dazugehören?

Ja, sowohl in Rothenburgsort als auch in Bergedorf (und damit wohl auch auf der gesamten Strecke dazwischen) gibt's jede Menge Eurobalisen und Ne14-Zeichen. Ob das streckenseitig schon aktiv ist, weiss ich nicht - von den S-Bahnen genutzt wird es soweit ich weiss noch nicht. > Und die ganzen > neuen Signale dazwischen hab ich auch noch nicht geschafft :/ Sind da in letzter Zeit Signale dazugekommen? Wo lohnt es sich näher hinzugucken, wenn ich in nächster Zeit am Hauptbahnhof Signale mappe? Gruß UncleOwen

[DE] Grenzen eines Bahnhofs / station limits
by UncleOwen 25 Aug '20

25 Aug '20

[ Since this is a question about mapping train stations in Germany, I start in German - english translation below ] Hi, ich frage mich gerade: Wie kann ich rausfinden, * von wo bis wo ein Bahnhof geht * was ist ESig, was ZSig, was ASig * ob das, was ich sehe ein oder zwei Bahnhöfe sind Ich weiss, dass ein Bahnhof in der Regel durch seine Einfahrsignale begrenzt wird wird. In vielen Fällen ist offensichtlich, was die Einfahrsignale sind - manchmal aber nicht. Deshalb suche ich Indizien, anhand derer man Einfahrsignale identifizieren kann. Ich kenne bereits: * ESig in Fahrtrichtung VOR der ersten Weiche, ASig VOR der letzten Weiche * Signale stehen im Bahnhof rechts vom Gleis, ausserhalb des Bahnhofs (incl. ESig) am zweigleisigen Strecken aussen * Signalbezeichnungen: * A, (B, C, ...) ESig der einen Richtung * F, (G, H, ...) ESig der anderen Richtung * doppelte Buchstaben für ESigs am Gegengleis * N, P für ASigs * alle anderen Buchstaben für Zsigs * Hauptsignale, die auf gleicher Höhe wie Trapeztafeln stehen, sind ESigs * Rangierhalttafeln stehen zwischen ASig und ESig der Gegenrichtung Was aber, wenn diese Indizien alle nicht zutreffen, bzw. sich widersprechen? Konkret geht es mir gerade um die Hamburger S-Bahn, Hauptbahnhof, Südende. Ist Berliner Tor eine eigenständige Betriebsstätte, oder gehört des zum Hauptbahnhof dazu? (Aktuell sind da so interessante Sachen wir block->intermediate->block gemappt...) Gruß UncleOwen ========================================================================= Hi, I'm wondering: How can I find out * where are station limits * which is an entry signal (ESig), which an intermediate signal (ZSig), which an exit signal (ASig) * whether what I'm seeing is a train station or two I know that a train station is usually limited by its entry signals. In many cases it is obvious what the entry signals are - but sometimes not. That's why I'm looking for clues that can be used to identify entry signals. I already know: * ESig in the direction of travel BEFORE the first switch, ASig BEFORE the last switch * When inside a station, signals are to the right of the track. When Outside the station on double-track lines on the outside * Signal designations: * A, (B, C, ...) ESig one direction * F, (G, H, ...) ESig the other way * double letters for ESigs on the opposite track * N, P for ASigs * all other letters for Zsigs * Main signals that are on the same level as trapezoid panels are ESigs * Shunting stop panels are between ASig and ESig in the opposite direction But what if all of these indications are incorrect or contradict each other? Specifically, I'm currently talking about the Hamburg S-Bahn, Hauptbahnhof, southern end. Is Berliner Tor an independent station or is it part of the main train station? (Currently there are so "interesting" things like block-> intermediate-> block mapped ...) greeting UncleOwen

Vacancy detection
by Björn Mahrt 22 Aug '20

22 Aug '20

Hi, just changed the wiki part for the curved switches and saw another discussable tag system: Would it be better to assign the railway:vacancy_detection tags as well to the tracks? That would have the advantage of not having to micro-map all axle counters to just know how the track is detected clear. The additional mapping of axle counters or insulated rail joints shouldn't be effected by that. Yet another advantage would be easier rendering possibilities. So I propose the following changes: + railway:vacancy_detection = [ no || insulated || counted ] on tracks. No changes on the railway=vacancy_detection tags for point objects. Best regards Björn
