[OSM-talk] FW: wikiproject rail?

[Steve Chilton]

Don't know what others think, but I have been doing some rail lines from
Landsat, and have done lines out of North London into Hertfordshire this
way (even easier with NickW's bringing down of Landsat to JOSM). Where
one has local knowledge I think this works fine, except v difficult in
heavily built-up areas. Also completed the lines through New Forest this
way (not yet tagged).

Cheers

But yes, I think it's pretty much impossible just from GPS sources.  
There are so many freight-only lines, routes where Virgin Voyagers and  
Pendolinos are the only trains (= no GPS reception), and so on.
