Chievres and other airfields near railways
 

I have been looking on the web for some time now and can not come across a map of train lines used by the Axis (or allies for that matter). I found where the rails use to be at Chievres by cross referencing books and GOOGLE MAPS. Being stationed there I can walk around and get a good visual.

Does anyone know of the major cities from Belgium back to Germany or a map specifically of the railways used by the Germans??

Any help would be appreciated as it would help put more impact into my paper about Chievres that I am writing.
