Hi
I have had a look at "newly" published Paris GTFS data which seems very good.
RATP 
http://data.ratp.fr/fr/les-donnees/fiche-de-jeu-de-donnees/dataset/offre-transport-de-la-ratp-format-gtfs.html 

However I was wondering if they use a non EPSG:4326 coordinate system or simply have an error in their output data?

The stops.txt look like: (see attachment)
stop_id,stop_code,stop_name,stop_desc,stop_lat,stop_lon,location_type,parent_station
4025438,,PONT DE NEUILLY - RIVE GAUCHE,,0.8532020217448393,0.0393479059605182,0,452832
4025439,,ALSACE,,0.8532639153293209,0.0392562301471691,0,8419
4025472,,GARE DE LYON - VAN GOGH,,0.8524587493261180,0.0414118995944202,0,439315
4025434,,LES GRAVIERS,,0.8531384698850659,0.0395542054222439,0,8296
4025435,,LES GRAVIERS,,0.8531301551998345,0.0395523141836901,0,8296

I cannot seem to find any EPSG system that would position this coordinate within Paris.
Do you have idea how to make sense out of this data?

Thanks
Marius

I feel like this is an error. Compare the 2 screenshots - 1 from the stops.txt file, another from a screenshot in the PDF file on the URL you posted

Somewhere along the way they've altered their exporter

We (Canal TP), had the same problem, we took the old stops.txt file, there is almost everything in it.
Here's the file we use in api.navitia.io : http://data.navitia.io/gtfs-paris-ratp-transilien-20131028.zip it's mix with transilien data.

They fixed this in an update this week. However, multiple lines are not active that should be. For exemple, T3A is apparently not running after october (which is obviously not true). 

We contacted them, obviously without response.

Hello,

I am using this feed, and there is always a lot to do. This time, everything is ending the 2013-12-31, and no update available (last update is 2013-12-12). To have the timetable for one day, I pick the one for the same day the week before 2014.
Don't wait some response from them. Only wait..
Good luck

have you tried to just replace the "." to a "," in the coordinates ?
i did and it seems to work well.
I'm using Excel 2013 powermap to locates data on a bing map.
