Local public transport

Hi all,

I would like to know from which database you take the stops and lines of public transport. That is, from the three belgian companies TEC, DE LIJN and STIB.
How often do you update the information?
I am very surprised by the accuracy of the information.

Thank you very much for your answer.

Marc, you had better post this on the mailing list, Belgian mappers scarcely visit this forum.
There is one, though, who comes here from time to time, and I think he is the same person who updates OSM with data published by De Lijn.
