First loco of the class 751 comed to Ostrava depot in 1999. The main reason for transfer to Ostrava was replacing of six-axle locomotives of the class 770/771. Depot (DKV) Ostrava has in year 2004 altogether 18 locomotives of the class 751 (751.009, 086, 088, 089, 093, 096, 098, 101, 105, 136, 143, 145, 148, 149, 151, 152, 220 and 374), but only nine are operated regularly. The most important role of these locos are hauling of coal trains and trains with empty waggons for coal. Therefore we can find them not only on SŽDC (Czech railway infrastructure manager) lines, but also of network of coal lines of private company OKD, Doprava.
