From the beginning in July 2005 the ministry of railways, railway construction fully open, passenger and cargo transportation, transportation equipment manufacturing and the four major fields of multiplex, advocate the reform of investment and financing. But as a result of national railway reform did not involve a series of coordinated reforms, enterprise investment returns is no guarantee that, although the railway in monopoly industries the non-public capital "opened a hole", but few responder. Other statistics show that China's existing railway mileage only 6% of the world railway mileage, per capita long rail length less than a cigarette! China's existing railway completed 24% of the world railway work. In 2003, for example, China railway to transport 33.26 million tons of cargo per kilometer, 7.9 times that of France, Germany, 7.8 times, 2.7 times of the United States. China railway freight volume, passenger turnover, transportation density are first in the world.

Since 2003, the high economic growth in China, the shortage of railway capacity is now the rapid development of national economy is obvious. Thus, in January 2004, the state council issued "the medium and long-term railway network planning" (hereinafter referred to as the "plan"). "Planning" requirement, China railway to realize leap-forward development. By 2020, the domestic railway operational mileage will develop by now, 73000 km to 100000 km, the construction of passenger dedicated line more than 12000 kilometers. In accordance with the objectives of the plan, by 2020, a total investment of about 2 trillion yuan, the railway infrastructure is in 100 billion yuan of above need money every year. The existing 73000 km railway of China, there are more than twenty thousand kilometers was built before liberation, in addition to more than twenty thousand kilometers, built in the fifties and sixties of the last century, and has been playing the main role. Among them, jingha, longhai and portions of jingguang, jinghu railway.

And provide data shows that the ministry of railways, in recent years, China's railway construction investment scale keeps basically is in 50 billion yuan to 60 billion yuan between, and the proportion of GDP has been in a state of decline. The conclusion of two groups of data shows that if you want to meet the national requirements, in addition to the national investment, every year in our country will also from other sources "raise" the funding gap of about 50 billion yuan. Too little investment, as a direct result of railway transportation capacity is insufficient, become one of the "bottleneck" of China's rapid economic growth.

The origin, the locomotive vehicle industry development

Rely on the train locomotive with machinery (commonly known as the locomotive traction waiting car, travel on the railway. The train is an important part of modern transportation, in addition to the passengers, the train is the main vehicle for long-distance transport goods, has a large capacity, low transportation cost advantages. In addition, in large coal mines, factories, also use the train internal transport task.

The train has a history of more than 100 years. Train was first appeared in 1814 by the British made in Stephenson. By 1825, he made the "power" 1 locomotive created when driving the highest speed of lu, 24 km per hour. In the decades that followed, the train gradually become important means of transportation, Europe and the United States began to large-scale building railways, mankind entered the railway age. The emergence of the train and railway so people can faster to travel long distances, can more easily from the far side of all the materials necessary to get and send the products to the distance to sales, these are greatly promote the development of production and improve the people's standard of living.

Early in the development of the train, the train's power is mainly provided by the steam engine on a motorcycle, motorcycle must carry on the work required for coal and water steam engine, the locomotive called steam locomotive. The first steam locomotive is British Richard trevi nabbed 1803 (figure 2), but not sure whether the locomotive running. Now people accepted the British George Stephenson as the "father" of steam locomotives, he designed the "journey" in 1825, the first formal operation of the railway was opened to traffic, stockton to darlington on railway load 53.7 tons, 15 miles (24 kilometers) per hour.

With the development of The Times, the modern train is no longer used heavy, low efficiency of the steam engine, and adopt the internal combustion engine or motor power, the locomotive called internal combustion engine cars and electric locomotives.

Diesel locomotive diesel engine and gas turbine engine, are its own carrying fuel, use of internal combustion engine to produce power through the drive traction train moving. Electric locomotive is built along the railway lines conveying power, motor power, is easy to control, the advantage of fast speed and low pollution. Electric locomotive as well as on the surface, some of the building in the city is under railway electric locomotive traction.

Railway construction is designed for the train. Track laid on the sleeper, sleepers can take the train through the pressure evenly to the face. Track cross-section is "work" word, both the enough strength, and saves material. The train was guided by the tracks.
