According to “Long-term railway network plan”and“T echnical policy of railway”,a comprehensive study on high power locomotive,heavy axle-load freight and new specified freight was conducted with consideration of long-term plan of railway delivery equipment. Its exploration and development was discussed. Based on the adaptability analysis of existing research results,a live load standard applied to bridges on Shanxi-Henan-Shandong railw ay thoroughfare w as proposed. For these bridges,the design axle load of the freight w as not less than 30 t.
