BEIJING, Jan. 25 (Xinhua) -- Heavy snow hit central and eastern China, causing delays and cancellations to trains and flights and triggering accidents on the roads.

Beijing Railway Administration canceled several trains from Beijing to Shanghai and cities in Anhui, Fujian, Henan, Shaanxi and Zhejiang on Thursday. Passengers can claim refunds on train tickets within 30 days.

A large number of cars, over 1,000 at the peak, were stranded on the road near the border of Anji and Ningguo, causing congestion stretching over 10 kilometers.

In Hangzhou, capital of Zhejiang Province, some 20 cars were badly damaged in a rear-end accident on an expressway in the city on Wednesday night.

Power supply companies in the province have been cleaning the electric wires to ensure no blackouts occur during rain and snow.
