Sorry, but the given address from OSM of CER.be is not correct. it states:
Bedrijf Community of European Railway and Infrastructure Companies, Montoyerstraat, Brussel, Brussel-Hoofdstad, Brussel Hoofdstad, 1000, België
But CER is located at Kunstlaan 53 according to their website cer.be
Sorry if I did it the wrong way, I thought it is open source, and I was given a way to correct it.
Also EIM (eimrail.org) was missing, so I tired to add it.
