My understanding is that wikipedia (alone) is not a valid source of data for OSM?
Yes. It is the main goal of OSM to do on the ground surveys. Only those surveys can guarantee high-quality data. These on the ground surveys made OSM become so good in Germany. More and more companies use OSM data in Germany because there is nobody with data of a similar level of detail. We, ORM in Germany, want to become this, too.
It is also not so worse than at OSM if an Wikipedia contributor ignores a few track sections where speed limit is lower due to a lack of refurbishment etc. But we ORM want to have data at this level of detail.
In Germany rail enthusiast like our maxspeed layer because it shows how fast trains really are allowed to run. Imaginary data can be found at Deutsche Bahn's network database (ugly to use and often wrong) ATTENTION: The following link brings you to a very ugly and unusable website. :-) http://stredax.bahn.de/ISRViewer/public_html_de/svg/index.html
