The liege train station is a big and beautiful train station, but it is not the best place to be if you have a tight schedule. We were transferring here and after a delay in the tracks, we had two minutes to make our next train. After jumping off our train we ran downstairs to see that there were a lot of tracks, but no signage showing you which way to which tracks. We ran the wrong way and then a man pointed us in the correct direction. We literally got to the train with seconds to spare and it closed right behind us. Besides that, we learned, on the way back through Liege, that the station is actually quiet nice and clean. There are places to get food and use the restroom.

Train station is busy, but clean. Signage is not very obvious
