Here’s an interesting pair of photos from 2009 that show two in-car strip maps that co-existed on Metro trains in Brussels. Together, they show the changes in the system that were occurring with the opening of track between the Delacroix and Gare de l’Ouest stations.

Apart from a new look to the map, the system itself seems to have been overhauled completely, with the previous lines “1A” and “1B” becoming “5” and “6”, amongst lots of other changes. Note also the four languages used on the informational stickers: French, Dutch, English and German!
