Just a note here that the source is over ten years old now and parts of the line has been resignalled. I think it would be a good idea to put in a request for newer version the document.

Kävinkin juuri eilen paikalla katsomassa mikä merkki tänne on asennettu. Tavallinen "P" eli yleinen se on. Päivitän vastaamaan tilannetta maastossa.

Ei mun pitänyt niitä poistaa, mutta vahingossa mennyt. Hyvä kun huomasit. Onneksi ne on helppo palauttaa.

Hyvä idea yhdistää parkkikset relaatiolla. Mutta tämä ei ole rakennus, koska on vain kevyet katokset. Tällöin riittää covered=yes. Mutta muutoin jatkakaa samaan malliin.

Same thing going on here as with changeset/170762787.

Haapamaki - Jyvaskyla is descriptive. Recommended use of name is for proper names only.

This looks like a mistake of using name-tag for a description, that is also redundant information as Orivesi-Seinäjoki is already tagged as a route relation.

osm.wiki/Names#Names_are_not_for_descriptions

Please don't do this. Route relations are used for mapping train services, not name tags.

We don't have a relevant name for this line, unfortunately, so it should be left without name.

Juu, mulla on käynyt tuossa virhe, jäänyt työmaamerkinnät huomiotta. Sori siitä.

To be more specific these two ways now form overlapping platform areas:

way/34007202

way/1420932643

While platforms can be mapped as a multipolygon it is not always necessary. I sometimes do it when there are multiple staircases and elevator shafts that need holes. But there is no real need to have holes for small shelters that are free standing on the platform, for example.

Now we have overlapping parts on platform 1 after this change. One is a multipolygon and another one is a closed way. Should have only one area.

Source for the signals is the Train Planning Network Model from Network Rail's open data feeds. Then I've fine tuned the locations with Bing aerial imagery.
