The station was used primarily by the Illinois Central Railroad , as the terminus for its main line from Chicago, but, over time, it also served a number of other lines, including the Southern Pacific Railroad and the Yazoo and Mississippi Valley Railroad .

该站主要用于由伊利诺伊中央铁路公司，作为该总站，以供其主线从芝加哥，但是，随着时间的推移，它也提供了一些其他线路，包括南部太平洋铁路公司和密西西比河谷亚祖和铁路。

With the uprising movement of Chinese railways and progress of electric railroad, the small tonnage full hydraulic railway crane becomes more urgently needed for development with characteristics of fast speed self-propelled running and high speed in train formation, hence, the high level requirement is resulted in terms of train formation and self-propelled running speed of railway crane. For 20t universal railway crane, features such as running with the load and weight lifting due to high hauling capacity are required besides hook lifting, bucket grabbing and magnetic panel lifting.

随着我国铁路事业的不断壮大，电气化铁路的发展，开发小吨位的自力走行速度快、回送速度高，能满足电气化线路的立杆作业的全液压铁路起重机迫在眉睫，对铁路起重机的回送和自力走行速度有了更高的要求。20t多功能铁路起重机，即具有吊钩、抓斗、磁盘吊3种功能外，还具有一定带载走行以及因牵引能力大也可作为吊车机使用。

Decades, the system does not always produce pipes, tiles, cement products and other traditional rod, but the development should be high (high-strength, high pressure) and large, new (new building materials and products) as a key to develop new products In detail: to develop high-strength prestressed concrete pile; apply to set up more than 110 kilovolt high voltage transmission lines and electrified railway lines, etc. Catenary large t m poles; application of new high-speed heavy rail with pre-stressed concrete sleeper; high-pressure , large-diameter prestressed concrete cylinder pipe; steel concrete and prestressed steel-concrete composite pipe; new type of reinforced concrete pipes, such as the mouth and socket bearing steel reinforced concrete pipes, square pipes, short-shaped pipes, common drains ; reinforced concrete inspection and; urban and rural construction using a variety of hollow interior wall panels and composite wall panels, concrete hollow block.

不能几十年一贯制生产管、瓦、杆等传统水泥制品，更应把发展高、大、新作为重点开发新产品，具体讲：大力发展预应力高强混凝土桩；适用于架设110 千伏以上高压输电线路和电气化铁路接触网线路等的大吨米电杆；适用高速重载铁路用的新型预应力混凝土轨枕；高压、大口径预应力钢筒混凝土管；钢板混凝土和预应力钢板混凝土复合管件；新型钢筋混凝土排水管，如钢承口和承插式钢筋混凝土排水管、方型渠、短形渠、共同渠；钢筋混凝土检查并；城乡建设用的各种空心内墙板和复合外墙板、混凝土空心砌块。

It is about a new railway crane for special purpose. With the ability of hoisting, walking and tawing, the crane can be used in the work of seting up pole and tower for railway electrification , and also, it can be owned by enterprises of factories and mines.

由此说明16t铁路专用起重机是一款新型铁路专用起重机：它的实用性能好并具有一定的行走能力，有一定的牵引能力，主要适用于铁路电气化线路电杆、铁塔的架设与施工作业的维护，同时也适用于厂矿企业自备用车。

According to national railway conference, the mileage of 200km/h railway have eached 6227km, and this is the same to the total mileage of 200km/h railway in Europe. In 2008, 10 Passenger dedicated railways with total mileage of 4100km, such as Jing-Hu, Jing-Shi,Shi-Wu and Jin-Qin and so on, will be constructed. In 3 -5years, constructions

根据全国铁路工作会议，目前，我国既有铁路经过技术改造，时速200公里及以上线路延展里程已经达到6227公里，相当于整个欧洲既有铁路提速到200公里以上线路的总和。2008年，京沪、京石、石武、津秦等10条客运专线将陆续开工，建设规模为4100公里。

The experiments are carried out at a bridge site and two buildings near railway tracks which are regarded as the point and line vibration sources.

实验结果表明，无论是作为桥墩的点振源，还是作为线路的线振源，铁路附近地面环境和建筑物地板的振动均随列车速度的提高而增大，随距线路的距离增加而减小，但在距线路一定的距离存在着一个振动放大区。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
