In the Fifties, the German State Railroad purchased a small series of new construction locomotives to supplement the outdated motive power roster chiefly of the Harzquer Railroad – but also of other meter gauge railroads. These units were a further development of road numbers 99 221 to 223 delivered in the Thirties. With an output of 700 horsepower, these 60 metric ton and 12.5 meter / 40 foot 8 inch long locomotives fulfilled the requirements set for them after initial teething problems were corrected. These locomotives are still currently running on the HSB and haul most of the traffic in the Harz Region – road number 99 236 too, which has been in continuous use for 65 years as of 2020.
