Veolia's subsidiary Dortmunder Eisenbahn tested new locomotives for their coil shuttle service between the steel-mills in Duisburg and the rolling-mills in Dortmund. (Yes, coils are already the product of a rolling-mill. But in Duisburg exists "compound-factories" of steel- and rolling-mills: Put liquid pig-iron in and get coils of heavy plates out. Sophisticated rolling will be done in Dortmund.) One of them was Veolia's E 37 507 a Alstom built type Prima. Here on 1st of November 2007 in Essen-Altenessen.
