[OSM-talk] User WJtW - railway track counts

[Colin Smale]

Oh by the way, user WJtW is still at it, most recently in Italy, filling
in loads of detail tags on railways. No idea where the information comes
from. But every segment he touches has tracks=N added, often with N>1 on
routes already mapped with individual tracks. 

@Michael Reichart, did you get a response from DWG about a possible
block on this user?

Getting the individual tracks right, with all the points/switches, sidings, crossovers etc is a helluva job. It is no surprise that people use a single way for a group of tracks as a first-order approximation. Adding tracks=N to that is not wrong, it's just incomplete.

Most of them are adding tags like gauge=1435 which may well be right (although I have no idea of his source for this). However on many occasions he has added tracks=N to the individual tracks where they are already mapped as N separate tracks. According to the wiki this should now be interpreted as N*N tracks. For example, the Channel Tunnel Rail Link south-east of London, is composed of two tracks (see [2] for a sample way). They are now both tagged with tracks=2, saying that each way represents 2 tracks, suggesting there are 4 in total, which is wrong.
