I remember once, when I was quite a small boy, being shown a level crossing in Brussels (soon after the war, it'd be) where the tram track in the street crossed the mian line railway on the level crossing. It might even have been dual guage tram-track (City - standard guage, Vicinal - metre guage) but I don't remember that. What I do seem to remember is the complexity of the overhead, where the tram wires mingled with the railway electification wires. I'm not certain of the details, though, and I wonder if the Belgian railways were electrified in the post-war era. Anybody know? Maybe my mischievous mind is bringing in complications that were not real! What was real was the level crossing.
