J'aime beaucoup les designs proposés. C'est assez proche de celui de la Stib pour les nouveaux trams à Bruxelles. Je sais que beaucoup critiquent les nouvelles couleurs de la Stib (moins visible, triste...) mais moi je les trouve magnifiques. Surtout qu'un tram est déjà assez visible de par sa taille, alors les critiques sur le manque de visibilité je ne les comprend pas trop.
Besides, Liège needs more efficient PT systems for both the city center and the outskirts now that city centers are growing again in Belgium.
A S-Bahn-like network for Liège, Ghent, Charleroi and Antwerp would be in the pipeline if the Belgian railway company had enough funds =>. A similar network for Brussels is already a decade late I think because of the skyrocketing costs. You can check it out here. They had to double most of the tracks since the Belgian network is busy (high density + its situation in Europe).
