I'm in the process of reviewing (and for the most part redrawing) the entire 
rail network in Flanders (to begin with, if the aerial imagery of Wallonia is 
good enough, I may extend it a bit that way, I've done all of West-Flanders 
and most of East-Flanders so far. It has slowed a bit since I don't have a lot 
of free time at the moment, but I hope to continue soon. If you come across 
some loose ends, that's where I'm at. Sources are the AGIV imagery, but I have 
a bit more knowledge about it since I'm an actual train driver. I try to work 
as accurate as possible, but it's a huge task (and I still have to do the 
entire port of Antwerp, ugh)... In the process I'm also adding maxspeeds, 
proper line refs and station/yard/junction names and codes, so you get nice 
maps on

On that aspect, I'm currently tagging everything except the industrial line as 
main line, and never branch line. Infrabel doesn't really make a distinction 
there, and I feel like creating one will just be too subjective. If someone 
has a better idea, let me know.
