China is a land of extremes, with over 1.3 billion people and a territory of more than 9.5 million square kilometres. At the same time, there is a huge gap between urban centres, cities over the million mark, like Beijing, Hong Kong and Shanghai and the rural areas, especially in the east of the country. And the transport of China can be termed as ‘extreme’. Finally, the most populous country in the world faces major challenges in providing transportation to a growing number of people striving for mobility. Mobility and flexibility in China are not only becoming commonplace in the major cities. There are also about 250 million migrant workers and an expansion of the transport network is vital for the ever-increasing economic growth of the country. Lufft’s compact weather stations WS400-UMB, WS500-UMB and WS600-UMB makes a viable contribution in this regard.

Only shortly before the end of the last year, China’s longest high-speed line in the world was opened for railway traffic. Now it only takes eight hours to cover a distance of 2,000 kilometres between Beijing and the economic stronghold of Guangzhou in the south of the Republic. For comparison, this trip used to take about 20 hours. This means that an average speed of the train is 300 km/h. Today, high-speed trains in China cover a total length of 9,300 kilometres, a network to be extended by the year 2020. The top speed Chinese trains is 400 km/h.

In order to ensure safe transportation of people and goods at these speeds, a close monitoring of environmental conditions is required. Tracks and trains should not be susceptible to damage from humidity, extreme temperatures and pressure. Wind speed is of particular importance, since the train speed must be adjusted to the wind strength. Thus, continuous monitoring of this parameter is essential. WS500-UMB and WS600-UMB are fastened to the wind measurement stations every five miles along the high-speed route. The wind data is processed in real time, so that a rapid response to unexpected changes in the wind force is possible. In this regard, it is important to ensure long-term stability of the system, as well as maximum accuracy and reliability, which are the major features of this Lufft product.
