Sichuan
–
In antiquity, Sichuan was the home of the ancient states of Ba and Shu. Their conquest by Qin strengthened it and paved the way for the First Emperors unification of China under the Qin Dynasty, during the Three Kingdoms era, Liu Beis Shu was based in Sichuan. The area was devastated in the 17th century by Zhang Xianzhongs rebellion and the areas subsequent Manchu conquest, during the Second World War, Chongqing served as the temporary capital of the Republic of China, making it the focus of Japanese bombing. It was one of the last mainland areas to fall to the Communists during the Chinese Civil War and was divided into four parts from 1949 to 1952, with Chongqing restored two years later. It suffered gravely during the Great Chinese Famine of 1959–61 but remained Chinas most populous province until Chongqing Municipality was again separated from it in 1997, the people of Sichuan speak a unique form of Mandarin, which took shape during the areas repopulation under the Ming. The family of dialects is now spoken by about 120 million people, in Modern Chinese, the name Sichuan has the meaning four rivers and this folk etymology is usually extended to list the provinces four major rivers, the Jialing, Jinsha, Min, and Tuo. In addition to its map and Wade-Giles forms, the name has also been irregularly romanized as Szű-chuan and Szechuan. In antiquity, the area of modern Sichuan was known to the Chinese as Ba and Shu, in reference to the ancient states of Ba and it was the refuge of the Tang court during the An Lushan Rebellion of the mid-8th century. The region had its own religious beliefs and worldview. The most important native states were those of Ba and Shu, Ba stretched into Sichuan from the Han Valley in Shaanxi and Hubei down the Jialing River as far as its confluence with the Yangtze at Chongqing. Shu occupied the valley of the Min, including Chengdu and other areas of western Sichuan, the existence of the early state of Shu was poorly recorded in the main historical records of China. It was, however, referred to in the Book of Documents as an ally of the Zhou and this site, believed to be an ancient city of Shu, was initially discovered by a local farmer in 1929 who found jade and stone artefacts. The Sichuan basin is surrounded by the Himalayas to the west, the Qin Mountains to the north, Qin armies finished their conquest of the kingdoms of Shu and Ba by 316 BC. Any written records and civil achievements of earlier kingdoms were destroyed, Qin administrators introduced improved agricultural technology. Li Bing, engineered the Dujiangyan irrigation system to control the Min River and this innovative hydraulic system was composed of movable weirs which could be adjusted for high or low water flow according to the season, to either provide irrigation or prevent floods. The increased agricultural output and taxes made the area a source of provisions, Sichuan was subjected to the autonomous control of kings named by the imperial family of Han Dynasty. Shu-Han claimed to be the successor to the Han Dynasty, in 263, the Jin dynasty of North China, conquered the Kingdom of Shu-Han as its first step on the path to unify China again, under their rule.

China Railway High-speed
–
China Railway High-speed is the high-speed rail service operated by China Railway. Hexie Hao is the designation for rolling stock operated for this service, All trains had been marked CRH, before being changed shortly afterwards to the Chinese characters 和谐号 on the centre of the head vehicles and the side of the walls of other vehicles. The introduction of CRH was a part of the sixth national railway speedup. All high-speed trains in use in China are named CRH. CRH1/2A/2B/2E/5 are expected to have a speed of 250 km/h. The new trainsets CRH380A have a maximum test speed of 416.6 km/h, the fastest trainset, CRH380BL, attained a maximum test speed of 487.3 km/h 302.8 mph). High-speed rail services were first introduced in 2007 operating with CRH rolling stock and those run on existing lines that have been upgraded to speeds of up to 250 km/h and on newer dedicated high-speed track rated up to 350 km/h. China Railway High-speed runs different electric multiple unit trainsets, the designs for which are imported from other nations and designated CRH-1 through CRH-5 and CRH380A, CRH380B, CRH trainsets are intended to provide fast and convenient travel between cities. Some of the trainsets are manufactured locally through technology transfer, a key requirement for China, the signalling, track and support structures, control software, and station design are developed domestically with foreign elements as well, so the system as a whole is predominantly Chinese. China currently holds many new patents related to the components of these trains. However, these patents are valid within China, and as such hold no international power. An order for 60 8-car sets had been placed in 2004, with the first few built in Japan and it is designed to have two versions, one with a top operating speed of 220 km/h, the other with a top operating speed of 160 km/h. They will be used on 200 km/h or 250 km/h Inter-city High Speed Rail lines, planned to service by 2011 CRH380A. CRH3C and CRH2C designs have an MOR of 300 km/h, and can reach up to 350 km/h, however, in practical terms, issues such as maintenance costs, comfort, and safety make the maximum speed of more than 380 km/h impractical and remain limiting factors. Based on data published by Sinolink Securities, some changes were made according to the most recent news. ^1 All CRH380B and CRH380C units to be delivered before 2012, ^2 All CRH380D units to be delivered before 2014. Before the introduction of technology, China conducted independent attempts to domestically develop high-speed rail technology. Some notable results included the China Star, but domestic Chinese companies lacked the technology and expertise of foreign companies, if using only their own resources and expertise, the country might need a decade or longer to catch up with developed nations

Track gauge
–
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails. All vehicles on a network must have running gear that is compatible with the track gauge, as the dominant parameter determining interoperability, it is still frequently used as a descriptor of a route or network. There is a distinction between the gauge and actual gauge at some locality, due to divergence of track components from the nominal. Railway engineers use a device, like a caliper, to measure the actual gauge, the nominal track gauge is the distance between the inner faces of the rails. In current practice, it is specified at a distance below the rail head as the inner faces of the rail head are not necessarily vertical. In some cases in the earliest days of railways, the company saw itself as an infrastructure provider only. Colloquially the wagons might be referred to as four-foot gauge wagons, say and this nominal value does not equate to the flange spacing, as some freedom is allowed for. An infrastructure manager might specify new or replacement track components at a variation from the nominal gauge for pragmatic reasons. Track is defined in old Imperial units or in universally accepted metric units or SI units, Imperial units were established in United Kingdom by The Weights and Measures Act of 1824. In addition, there are constraints, such as the load-carrying capacity of axles. Narrow gauge railways usually cost less to build because they are lighter in construction, using smaller cars and locomotives, as well as smaller bridges, smaller tunnels. Narrow gauge is often used in mountainous terrain, where the savings in civil engineering work can be substantial. Broader gauge railways are generally expensive to build and require wider curves. There is no single perfect gauge, because different environments and economic considerations come into play, a narrow gauge is superior if ones main considerations are economy and tight curvature. For direct, unimpeded routes with high traffic, a broad gauge may be preferable, the Standard, Russian, and 46 gauges are designed to strike a reasonable balance between these factors. In addition to the general trade-off, another important factor is standardization, once a standard has been chosen, and equipment, infrastructure, and training calibrated to that standard, conversion becomes difficult and expensive. This also makes it easier to adopt an existing standard than to invent a new one and this is true of many technologies, including railroad gauges. The reduced cost, greater efficiency, and greater economic opportunity offered by the use of a common standard explains why a number of gauges predominate worldwide

Chengdu, formerly romanized as Chengtu, is a sub-provincial city which has served as capital of Chinas Sichuan province. It is one of the three most populous cities in Western China, as of 2014 the administrative area houses 14,427,500 inhabitants, with an urban population of 10,152,632. At the time of the 2010 census, Chengdu was the 5th-most populous agglomeration in China, with 10,484,996 inhabitants in the area including Xinjin County. The surrounding Chengdu Plain is also known as the Country of Heaven and its prehistoric settlers included the Sanxingdui culture. It was the capital of Liu Beis Shu during the Three Kingdoms Era, after the fall of Nanjing to the Japanese in 1937, Chengdu briefly served as the capital of China. It is now one of the most important economic, financial, commercial, cultural, transportation, Chengdu Shuangliu International Airport is one of the 30 busiest airports in the world, and Chengdu Railway Station is one of the six biggest in China. Chengdu also hosts many international companies and more than 12 consulates, more than 260 Fortune 500 companies have established branches in Chengdu. In 2006, China Daily named it Chinas 4th-most-livable city, the name Chengdu is attested in sources going back to shortly after its founding. The present spelling is based on pinyin romanization, its Postal Map romanization was Chengtu and its former status as the seat of the Chengdu Prefecture prompted Marco Polos spellings Sindafu, Sin-din-fu, &c. and the Protestant missionaries romanization Ching-too Foo. Although the official name of the city has remained constant, the area has sometimes taken other names. The city logo adopted in 2011 is inspired by the Golden Sun Bird excavated from the Jinsha Ruins, archaeological discoveries at the Sanxingdui and Jinsha sites have established that the area surrounding Chengdu was inhabited over four thousand years ago. At the time of Chinas Xia, Shang, and Zhou dynasties, in the early 4th century BC, the ninth king of Shus Kaiming dynasty relocated from nearby Pi County, giving his new capital the name Chengdu. Shu was conquered by Qin in 316 BC and the settlement refounded by the Qin general Zhang Yi, under the Han, the brocade produced at Chengdu became fashionable and was exported throughout China. A Brocade Official was established to oversee its quality and supply, after the fall of the Eastern Han, Liu Bei ruled Shu, the southwestern of the Three Kingdoms, from Chengdu. His minister Zhuge Liang called the area the Land of Abundance, under the Tang, Chengdu was considered the second most prosperous city in China after Yangzhou. Both Li Bai and Du Fu lived in the city, Li Bai praised it as lying above the empyrean. The citys present Caotang was constructed in 1078 in honor of an earlier, more humble structure of that name erected by Du Fu in 760, the Taoist Qingyang Gong was built in the 9th century. Chengdu was the capital of Wang Jians Former Shu from 907 to 925, the Later Shu was founded by Meng Zhixiang in 934, with its capital at Chengdu
