Arnold HN2526 DR, electric locomotive class 251, red livery with small decor line, period IV N Gauge

251 012-1, the prototype of the new Arnold model HN2526, can be admired today as a museum locomotive at BW Weimar. Until the timetable change in 2004/2005, it was in service together with its sister engines on the famous Rübelandbahn – whether in front of heavy freight trains, as a pusher locomotive behind them or in front of local trains on the Blankenburg – Königshütte line in the Harz Mountains.
