Thank's for your comment ! Infact in 5 years picturing these trains I never thought about ore, only coal. Only sometimes wondering that these wagons were not filled up to top, as coal trains (or coke, which is lighter) mostly are. This should be coal/coke: http://www.railpictures.net/viewphoto.php?id=251930&nseq=38
Yes, that's a nice comparison. Most of the iron ore trains were pulled (and maybe still are) by BR 151 with automatic couples, as I've seen on Youtube, now most of them are replaced by BR 189. Nice one with the "black bird" too.
nice picture, this is indeed an iron ore train which is travelling from Venlo to Dillingen. They used to be pulled by Br151's but since 2011 they are pulled by Br189's from Rotterdam to Dillingen via the Betuweroute.
