The problem is you will find not with the metal railway carriages but with the coating on the windows. I find my GPS works well in almost all carriages (I get accuracy typically of 6 m).
Occasionally though, I get no signal in carriages that have been fine in the past, the only difference seems to be in the glass, some of which has a very obvious metallic coating. Maybe you could go to a station and try it out in a cariage that was waiting to leave. 2009/10/7 John Henderson <[email protected]> > Has anyone had success using a GPS unit inside a metal railway carriage > to map a railway line? > > I notice that parts of the main line between Sydney and Melbourne are > missing, eg: > > http://www.openstreetmap.org/?lat=-34.7446&lon=147.886&zoom=14&layers=B000FTF > > I'd consider doing the trip on the XPT if someone has proven it's viable. > > And I've also had to move the railway line aside quite a distance when > accurately adding roads in the Yass area. > > _______________________________________________ > Talk-au mailing list > [email protected] > http://lists.openstreetmap.org/listinfo/talk-au >
