Based on the operation of 421 sets of ND5 locomotives with a total turnover of 597 billion tons of freight trains as of 1988, this paper makes a more comprehensive analysis of the economic benefits, locomotive operation level, operation methods, brake selection and quality problems of ND5 locomotives. Analysis. That the purchase of ND_5 locomotive fee, and then 5 to 6 years can be fully recovered, but also made ten points of use, maintenance, management and other aspects of the proposal. It is recommended to promote the rectangular operation of oil-saving methods N7, N8 and idling alternately. It is suggested to study the reasonable standards of oil quality control.
