For E+H work real railwaymans. They are pround about the history of their company. They are right, caused by the interesting technical solutions which are used in the past and still today (and IMHO by the genious yellow... :-)). Near the administration building are some interesting examples placed: E+H 183 Henschel-type EDE 1000/500, E+H 109 a "Thyssen-Crocodile" built by Jung and E+H 83 an electric-loco with batteries for tracks without catenary built by August Thyssen Hütte. Unfortunately this little "museum" in good shape isn't reachable for the public.
