[Talk-GB] Railway edits in the UK that could perhaps benefit from a bit of checking.
An anonymous note adder (http://www.openstreetmap.org/note/267719) and someone on IRC noticed some problematical railway edits near Sutton-in-Ashfield: http://www.openstreetmap.org/way/311380489#map=15/53.1247/-1.2346&layers=N It looks like an attempt to dual the Robin Hood line went a bit wrong and ended up slicing through an industrial estate and some areas of housing (though I'm sure it was "cock-up rather than conspiracy" as Sir Bernard Ingham would have said). Looking at some other edits in the same changeset, there are some other, less obvious, issues too, which I've added to the changeset discussion: http://www.openstreetmap.org/changeset/26590071 The most obvious problem seems to be "tracing the railway in but not joining properly to other features (such as crossings)". Some information (e.g. "cutting=yes") has also been lost. Another local changeset: http://www.openstreetmap.org/changeset/26587435 has some similar issues. There have been a number of other edits, some with rather a lot of deletions in them, including: http://www.openstreetmap.org/changeset/26613977 All of these changesets could probably also benefit from a review from local mappers to identify potential issues.

Re: [Talk-GB] News Paper Article
There have been a number of articles in the Guardian about Google maps. It was therefore good to see something on Openstreetmap in this Friday's edition .

Re: [Talk-GB] Mapping turn lanes on major roads
The example you give has not been well mapped and the mapper needs to be contacted to explain about lanes. There is not an extra physical road between the carriageways so it should not be added as such.

Re: [Talk-GB] Mapping turn lanes on major roads

This is what I started using after first using OsmAnd and seeing lane hints on some roads, and wondering how it knew. I started adding them elsewhere (not many so far). As per Andrew's reply, I also tend to reserve separate ways for some physical separation greater than a white line (so a turn lane which becomes a slip road would become a separate way where they fork and the number of lanes on the main carriageway would be reduced accordingly).
