[iRail] UK railway data

Tue Aug 21 16:53:10 UTC 2012

Cool. You're my hero.

De Lijn is about 1Gb of data as well if I'm not mistaken, and importing it takes about 2 hours. 
If we can wget those 2Gb once per week and import it at night, that'd be great. (*)

How much data does it hold by the way? I didn't really check it in detail.
All of Great Britain? Just UK? What about London underground? 

That 5Mb archive holding updates, what does it actually contain? 

(*) This brings me to another thing though: to prevent inconsistent/duplicate data, we drop both De Lijn & STIB schema and recreate/reimport everything. 
Dropping just the data takes significantly longer. 
However, this brings a problem that, if anyone would request the data at that period of time, the database would be empty. Do you have a solution/idea for this? 
This is something Maarten Cautreels worked on. 

Thanks again!

I have to update geolocation because my coordinates transformation script wasn't doing so well (I had to transform from northing/easting to latitude/longitude).

So if you want to provide up-to-date informations via data.irail.be I can write a wget/parse/store daily cronjob to get it done.
