我国目前现有铁路线数十万公里,加上煤炭、钢铁、电力、石油、化工等行业的铁路专用线,总长已近百万公里。未来十年是我国铁路高速发展时期,“十一五”期间,我国投入修建铁路资金达2万亿人民币。加之地方铁路、矿区铁路专用线的修建,将使国家铁路线总里程迅速发展。铁路线上每公里所用螺帽达8000个,加上电力设施、公路桥梁、公共设施、石油管道、军用设施等使用的螺帽,用量十分巨大。由于战线太长,给管理上带来了严重的困难。数十年来,整个国家的各条铁路线上的道轨配件时常被盗,偷盗铁路器材现象在各铁路线上都时有发生,这为列车行车安全埋下了隐 At present, there are hundreds of thousands of kilometers of existing railway lines in our country. Coupled with the special railway lines for coal, steel, electricity, petroleum and chemical industries, the total length is nearly one million kilometers. The next decade is the period of rapid development of China’s railways. During the 11th Five-Year Plan, China has invested 2 trillion yuan in railway construction. Coupled with the construction of local railways and mining railway lines, the total mileage of national railway lines will rapidly develop. There are 8,000 nuts per kilometer on the railway line, and the amount of nuts used in power facilities, road bridges, public facilities, oil pipelines and military facilities is extremely large. Too long a battlefield has brought serious difficulties in management. For decades, the railroad tracks and accessories on various railway lines throughout the country have been stolen frequently, and the phenomenon of stealing railway equipment has occurred from time to time on all railway lines, laying a hidden barrier to the safety of train traffic
