XI ' an, the first equipped with the fastest domestic high-speed rail: a top speed of 380 km-high speed train-IT information
At about 10 o'clock in the morning, two sets of "Dolphin"-front CRH380B-high-speed EMU arrived at the marsh of Xian railway maintenance depot. This is equipped with the fastest domestic high-speed rail cars for the first time, maximum operating speeds of 380 km per hour, September zhengxugaotie opened, will serve the railway opening Xian to Shanghai, Fuzhou, Hefei and other high-speed rail lines.
Maximum test speeds of over 400 km
Both sets of CRH380B-type high speed emus from the Tangshan locomotive and rolling stock company line rolled off are CRH3C based on the research and development of new generation high speed emus, to raise the maximum operating speeds of up to 350 km 380 km, the maximum test speed of over 400 km, is the main rail passenger cars.
CRH380B optimum design of high-speed EMU front using the "Dolphin" type locomotive, beautiful shape smooth, reduced at high speeds air resistance. China business news reporters saw on both sides of the front line through the entire vehicle "Groove". The staff, the "grooves" trains were greatly reduced the aerodynamic lift, increases the stability of the caboose.
Distribution of more than 1000 sensors throughout the car up and down temperature of critical systems and parts of the train, speed, acceleration, pressure, insulation and other monitored parameters, when the detected value exceeds the limit value, the train monitoring system analysis, provides level 5 security response mechanisms, trigger a train fault protection.
Disabled toilet set in baby care set
Inside, the entire vehicle with fully enclosed green-for-air automatic air conditioning system, used in all energy-saving LED lighting, full application of green energy technologies.
In addition to setting the disabled riding area at one end of the dining car compartment also has a special disabled toilets, press the auto lock button, the door automatically opens, door closes automatically. Disabled toilet with handrail, there was a shelf above, pull down seconds after baby care, mothers can give your baby easy diaper changes.
With more than more than 20 city of XI ' an high-speed direct-attached
It is reported that the configuration of CRH380B for the first time in XI ' an EMU, mainly after the service opened in September zhengxugaotie of XI ' an additional high-speed trains. Xian railway Bureau will add at least 29 groups this year CRH380B EMU. Zhengxugaotie opened, with Xian as the hub of the West Rail for the first time with the Beijing-Shanghai high-speed railway network. At that time, XI ' an and Shanghai, Nanjing, Qingdao, Shenyang, over more than 20 large and medium cities, such as gaotiezhilian for the first time.
A case study of Qingdao, and now only more ordinary train from Xian to Qingdao, took in 17-23 hours, zhengxugaotie opened, is expected to reduce to around 8 hours.
西安首配国内最快高铁：最高时速380公里 - 高铁 - IT资讯
上午10时许，两组“海豚”型车头的CRH380B型高速动车组抵达位于西安草滩的西安铁路局动车段检修库。这是西安首次配备国内最快的高铁车型，最高运行速度可达每小时380公里，9月份郑徐高铁开通后，将服务于西安铁路局加开的西安至上海、福州、合肥等高铁线路。
最高试验时速超过400公里
这两组CRH380B型高速动车组刚从唐山机车车辆公司生产线下线，是在CRH3C基础上研发的新一代高速动车组，最高运营时速由350公里提高到380公里，最高试验时速超过400公里，是我国高铁客运的主力车型。
CRH380B型高速动车组车头采用了优化设计的“海豚”型车头，外形流畅优美，能够减小高速运行时的空气阻力。华商报记者看到，车头两侧有一条贯穿全车的“凹槽”。工作人员介绍，这种“凹槽”大大降低了列车的气动升力，增加了尾车的稳定性。
1000多个传感器分布在全车上下，对列车的关键系统和部位的温度、速度、加速度、压力、绝缘性能等参数进行监测，当检测值超出安全限值后，列车的监控系统会分析判断，提供5级安全响应机制，触发列车的故障保护动作。
残疾人卫生间里设婴儿护理台
内装方面，全车采用全封闭的绿色换新风自动空调系统，全部采用LED节能光源照明，绿色能源技术的全面应用。
除了设置残疾人乘坐区，在餐车车厢的一端还有一个特殊的残疾人卫生间，按了自动开关门锁按钮，门可以自动打开，进去后自动关闭。带扶手的残疾人专用座便器，上方有一块搁板，拉下来后秒变婴儿护理台，妈妈们可以给宝宝很方便的换尿片了。
西安将与20余城高铁直连
据悉，此次西安首次配属CRH380B型动车组，主要服务于9月郑徐高铁开通后西安局加开的各次高铁列车。今年西安铁路局将至少增配29组CRH380B型动车组。郑徐高铁开通后，以西安为枢纽的西部高铁首次与京沪高铁互联。届时，西安将与上海、南京、青岛、沈阳等20余个大中型城市首次实现高铁直连。
以青岛为例，现在从西安去青岛只有多趟普通列车，耗时在17到23个小时之间，郑徐高铁开通后，有望缩短到8小时左右。
