99.5901, one of the original Nordhausen - Wernigerode Eisenbahn 0-4-4-0T Mallets, was still working on the line it was built for, 115 years later. The 1897 vintage loco was turned out to work a special train from Wernigerode to Brocken on 7 October 2015 and photographed between Steinerne Renne and Drängetal, climbing towards Drei Annen Hohne with three old coaches in tow.
