The author:(作者)aaapublished in(发表于) 2013/12/16 0:34:16 Chongqing new subway stops from the surface does not exceed 30 meters， half in and out of time
Regular subway passengers may have such a feeling---down from entrance to the station was too far away, both time and energy. Especially majiayan, red land typical of this kind of deep-hole subway stations, depths reaching more than 60 meters, only inbound takes 5-10 minutes. Why Metro station so far? Can close off the ground a little while?
Yesterday, the Chongqing evening news reporters in the city rail group driven by innovation and harmonious development of urban rail transit system at the meeting was informed that future Chongqing new subway stops are less than 30 meters from the ground, passengers in and out of time in half.
Enhanced capacity subway ramp
Urban rail transit (Group) limited company Zhong Jianhua, Chairman introduced, the city's existing line 1, Line 6, train climbing ability in 30%. , That is, the height is 30 metres altitude 1000 m train. "This is national standards, is appropriate in many Plains cities nationwide, but in mountain city Chongqing has an impact. ”
Zhong Jianhua said, Line 1 line two eling junction station a short distance, metro cars from the intersection of two stand up there is no way to move on to eling, eling can hit more than 40 meters under the ground. This not only increases the difficulty of construction, economy, ladder usage, leading to passenger access to the station is not convenient. When faced with an emergency, evacuation and rescue of passengers is also difficult.
Do? Zhong Jianhua said that the municipal rail group through years of trial and error and continue to develop, and finally in the same premise of trains and technology, train climbing capacity increased to 50%. This means that the same distance, train climbing height can be increased by 20 meters. "In the future our Metro stations are all within 30 metres from the ground, saving construction costs, facilitate passenger accessibility. "This design will be used in New Line 4, Line 5, line for line, circle and line Line 10 built next year, including future plans for additional lines of the Metro system.
Subway trains to achieve cross-line operation
Line 4, Line 5, line for line, link is under construction and the construction next year of Line 10 subway, will also achieve cross-line operations. This method of implementation without having to out line transfer, will gain popularity on the other new track in the future. It is reported that Chongqing pioneered ways of operating will be in this country.
Zhong Jianhua said, now Metro are one-way operation in major cities throughout the country, did not take into account network construction. Chongqing will be launched in the first set of cross-line operation, total operating line and crossed the line in one of the interconnection network business model, future will form a large mass transit network.
According to reports, called crossing the line operations, is currently a single track on the basis of platform edges add a cross the line track. In future, this cross the line track through the dedicated Express, passenger traffic in small sites do not stop at.
Urban fast-track access to the rail network
Urban fast track connecting suburban railways, the main city rail transit mode of transportation. Zhong Jianhua said that the future urban fast-track conversion of railways and rail transport---trains on the railroad, while in the main city track.
How does it do this? Zhong Jianhua introduced, first on the speed, subway generally 100 km/h or so, high speed rail at over 200 km, urban fast track at 140 kilometers faster than the subway, slower than the high speed rail, applies between main city suburb of short-line operation and long-term operation.
Secondly, urban fast track will introduce a dual-flow system. Main City subway used 1500 volt DC power supply, rail use 25,000 volt AC power supply, fluids differ between trains cannot, of course, interoperability. Urban fast-track double-current system has both similarities, coupled with a unified standard rail, will be able to drive unimpeded to the railway when the train, rail traffic as some kind of underground, line to Line 4, Line 5, Line 10, line and circle to achieve cross-line operations. It is learnt that the line Line 5 extension to jiangjin section it is possible to adopt this mode of operation.

经常乘坐地铁的乘客也许都有这样一种感觉———从出入口下到站台距离太远，既耽误时间又消耗体力。尤其是在马家岩、红土地这一类典型的深洞地铁站，深度达到了60多米，仅出入站就需花5~10分钟。为什么要把地铁站建这么深？能不能离地面近一点呢？
昨日，重庆晚报记者在市轨道集团创新驱动与城市轨道交通多制式协调发展座谈会上获悉，今后重庆新建地铁站离地面都不超过30米，乘客进出时间可节省一半。
地铁爬坡能力得到提高
市轨道交通(集团)有限责任公司董事长仲建华介绍，我市现有的1、6号线列车的爬坡能力都在30%。，也就是说，列车行驶1000米爬升的高度是30米。“这是国家标准，在全国很多平原城市是适合的，但在重庆这样的山地城市就有一定影响。”
仲建华举例说，1号线两路口站到鹅岭站距离很短，地铁车辆从两路口站出来还没有爬升到很高就到鹅岭站了，所以鹅岭站就只能挖到地面下40多米的地方。这不仅增加了建设难度、经济支出、扶梯使用量，还导致乘客进出站不方便。一旦遇到突发事件，乘客疏散救援也有一定难度。
怎么办？仲建华说，市轨道集团通过多年来的摸索和不断研发，终于在采用同样列车和技术前提下，将列车爬坡能力提高到50%。。这意味着同样的距离，列车爬坡高度可以增加20米。“未来我们的地铁站都将在离地面30米以内，既节省建设成本，又方便乘客出入。”这种设计将运用在新建的4号线、5号线、环线和明年开建的10号线，包括未来规划的其他地铁制式的线路。
地铁列车将实现跨线运行
正在建设的4号线、5号线、环线和明年开建的10号线，还将实现跨线运营。这种不用出车就实现线路换乘的方式，今后将在其他新建轨道上得到普及。据悉，这种重庆首创的运营方式还将在全国推广。
仲建华表示，现在全国各大城市的地铁都是单线运营，没有考虑网络化建设。重庆将在国内首个推出集跨线运营、共线运营和越线运营于一体的互联互通的网络化运营模式，未来将形成一张大的轨道交通网络。
据介绍，所谓越线运营，就是在目前的单条轨道基础上，在站台边多增加一条越线轨道。今后，这条越线轨道专供快车通过，在客流量小的站点不停靠。
都市快轨将接入轨交网络
都市快轨是连接市郊铁路、主城轨道交通的交通方式。仲建华说，未来都市快轨将实现铁路和轨道交通的转换———在铁路上是火车，在主城轨道上又能当地铁。
它是怎样做到的呢？仲建华介绍，首先在时速上，地铁时速一般在100公里左右，高铁在200公里以上，都市快轨在140公里左右，比地铁快，比高铁慢，适用于主城短线运营和市郊长线运营之间。
其次，都市快轨将采用双流制。主城地铁采用1500伏直流电供电，铁路采用25000伏交流电供电，流质不同，列车之间当然无法互联互通。都市快轨的双流制拥有两者的共性，加之采用统一的标准轨道，就能畅通无阻地开到铁路上当火车，在轨道交通上当地铁，还能和4号线、5号线、10号线和环线一样实现跨线运营。据悉，5号线支线到江津的路段，就有可能采取这种运营方式。
