Here are some images we have created - a few of them today in response to your query, others in the past few weeks. http://www.flickr.com/photos/itoworld/tags/railway/ There are some places where there certainly appear to be gaps and I have suggested that people add notes to the images where they see them, or indeed possibly they should add them to OpenStreetBugs (http://wiki.openstreetmap.org/wiki/Openstreetbugshttp://www.flickr.com/photos/itoworld/tags/railway/ ) It would also be very interesting for someone to get hold of the European train timetable and do a check to see how many stations are missing and for how many services there are not suitable routes - This could probably be done by a university legally and they should be able to publish the resulting map without getting into licence problems - Possibly a company could also do that - not sure about that, but UCL did a comparison of OSM and OS data in the UK and determined that this was ok from an OS licence perspective. http://povesham.wordpress.com/2008/08/19/openstreetmap-quality-evalution-and-other-comparisons/ It is my experience elsewhere that it is only when the quality tools are in place that people are able, and motivated, to do the completion of the dataset.
