The railway system plays a leading role in traffic and transportation system and its transportation capacity has been improved from time to time , and the hump facilities have developed quickly in the railway marshaling stations too . the transformation and escalation project of the hump is frequent , so the transportation capacity of the " spots " has been improved greatly and adapted to the continued growth of traffic 做为交通运输支柱行业的铁路的运输能力也不断提高，铁路编组站驼峰设备也得到迅速发展，驼峰改造和升级工程频繁，极大地提高了铁路的“点”上能力，适应了车流不断增大的需要。
Prevention of railway noise pollution state environmental protection administration and ministry of railway have jointly issued the notice on enhancing railway noise pollution prevention , requesting the whistling of the trains travelling in urban areas and the loud speakers of the railway stations , marshalling yards , and switchyards should be controlled 铁路噪声污染防治国家环保总局与铁道部联合发布了《关于加强铁路噪声污染防治的通知》 ，要求控制市区运行的火车鸣笛及火车站、编组站、调车场指挥作业的高音喇叭。
Abstract : the paper introduces the erection of the steel box girder of a long - span steel box - concrete composite bridge using broad double guide beam without affecting the normal operation of electrified railway and marshalling yard under the bridge , including construction plan , design of gantry crane and guide beam , as well as key points of construction technology 文摘:介绍在保证电气化铁路、编组站场正常运营情况下，运用宽幅式双导梁解决大跨度钢箱混凝土结合梁桥的钢箱梁架设技术难题，重点阐述了施工方案，龙门吊、导梁设计，工艺要点等。
Beijing - kowloon railway , guangzhou - meizhou - shantou railway cross in the city , with a marshalling station at longchuan , which is the biggest one in south china ; state highway 105 and 205 run through the city ; on the waterway of dongjiang can sail hundred - ton cargo ships to huizhou , dongguan , and guangzhou . the city is favorably located with convenient communications ; so it may draw in economic radiation from all directions , exploring markets and resources of all kinds 京九铁路、广梅汕铁路在市内交汇并线，在龙川设有华南地区最大的编组站； 105 、 205国道贯通全市；东江航道可通百吨级货轮，南达惠州、东莞、广州。区位优越，交通便利，可以接受多方面的经济辐射，开拓各种资源和市场。
With continuous spread of industry - mine enterprise production scale , there are short of transportation dispatching capability for these old subsystems of steel yard provided for themselves being outdated technology and not integrated , so the problem is more and more becoming the holdback of industry - mine enterprise development 随着工矿企业生产规模的不断扩大，由于企业自备铁路编组站原有的各个作业子系统技术落后且各自独立，从而存在运输调度能力的不足，使之成为工矿企业发展的障碍。
The automatization technology of transportation scheduling job system is no doubt effective way to solve the question , and the fast development of computer control technology information technology and trunking communication technology provides good material technology base , to make yard and even the whole enterprise go forward integrated automation job period steadily 运输调度作业系统自动化技术无疑是解决这一问题的有效手段，而计算机控制技术、信息技术和集群通信技术的飞速发展，为运输调度作业自动化提供了良好的技术物质基础，使得编组站乃至整个企业可稳步迈向综合自动化作业时期。
