The Mining and Railway Centre of Oignies
A Living Railway Museum and the epic story of Coal mining
The town of Oignies has an excellent Web site where you will find a great deal of information on the town (partially in English). If you look at google maps and satellite images , you will see "Centre Denis Papin" (the large red-roofed building) between Rue Emile Zola and Avenue des Sports. It is also possible to see the standard gauge railway lines entering the club site.
There is also a good entry for Oignies in Wikipedia
