Abstract：The article compares the typical faults of the C70E（H） -A 10 Ooo-ton heavy haul train formed by railway freight cars running on Watang-Rizhao line and those of ordinary trains and analyzes in depth the faults such as wear of wheels，cracks of coupler knuckles and wear of brake shoes occurring in the C70E（H） -A 10 000- ton heavy haul train. Considering the operation situation，it proposes the quality assurance measures for key links，the regular organization of maintenance and the operation coping strategies in the aspects of maintenance of axle，bogies and cars so as to ensure the performance of the C70E（H） -A 10 ooo-ton heavy haul train，reduce the fault rate and increasethe service eficiency of the cars.Meanwhile，it give suggestions related to the form of train formation，the R&D of wireless network transmisson of braking signals，improvement of coupler knuckles and other aspects， providing a reference for further optimizing the technologies of the C70E（H）-A 10 000-ton heavy haul train.
