Best way to query train lines?

Question

Hello,

I'd like to get all the disused train lines in France.

The following query can time-out, and iOT isn't happy if I run it again ("Check your quota"):

[out:json][timeout:25];

//Metropolitan France 1403916
rel(1403916);
map_to_area -> .searchArea;

(
  way[railway~"(disused|abandoned)"](area.searchArea);
);

out geom;

Is there a better way, possibly using the command-line?

Thank you.

Accepted Answer

If you're after actual closed railways the popular tags are:

area(3600008640);
way[~"(disused:railway|abandoned:railway)"~"^rail$"](area); 
out geom;

I've used a smaller relation for ease of explanation. For the whole of France & Corsica use area(3601403916); (~20mb)

If you're specifically after tags which aren't the above then you'll almost certainly need to split your search into smaller areas as using the 'railway' key searched all values for it, which returns quite a bit more data than just 'rail'.

Addendum to original answer:

You may get away with calling this just once, for the whole of the country (~40mb). The Regex '^' & '$' means the search has to start & end with those words so, in fact, it's only searching for whole words.

area(3601403916);
way[railway~"^(disused|abandoned)$"](area);
out geom;

I'll give it a try, and see if OT doesn't complain with my querying too much data.
