China Daily reporter Zhao Lei watches the countryside hurtle past as he travels in comfort and style on the world's longest high-speed rail link.

The train left Beijing, with patches of snow dotting the capital, at 9 am on Wednesday before it whizzed past green rice fields when it crossed the Yangtze River four hours later. At 5 pm, it arrived in flower-dotted, subtropical Guangzhou, where the temperature was 20 C higher than in Beijing when the trip began.

The world's longest high-speed rail link, connecting Beijing and Guangzhou, the capital of Guangdong province, became fully operational on Wednesday.

The 2,298-km line cuts the journey time from more than 20 hours to around eight and connects 28 cities, including five provincial capitals.

The designated speed of the route is 350 km/h, although the initial operating speed is around 300 km/h.

Fifteen minutes after the bullet train departed from Beijing West Railway Station, the speedometer hit 300 km/h and the speed was maintained for almost the entire journey, the exception being the section between Xuchang in Henan province and Hengdian in Hubei province, because of heavy snow.

The CRH380A(L) train, which is in service on the new line, has undergone extensive tests around the country, so its reliability is assured, said Wu Donghua, a senior engineer at CSR Sifang Co, one of China's biggest manufacturers of bullet trains.

The train's internal temperature was maintained at a comfortable level, with a low of 18 C.

The train is equipped with special washrooms for the disabled and can serve four different types of cuisine.

Zhang Wei, an electrical engineer from Cangzhou in Hebei province, left home at night and traveled three hours by coach so he could "have the unforgettable experience of being on the first train on the line".

He was impressed with the facilities and service, but not with the price. His first-class seat cost 1,383 yuan ($221), more expensive than an economy-class air ticket. Seats in the second-class cabin cost 865 yuan.
