BEIJING, May 13 (Xinhua) -- The construction of an express rail line linking Harbin and Jiamusi cities in northeast China's Heilongjiang Province has been completed, according to sources with China Railway Group Limited.

The express railway will allow trains to run at 200 kilometers per hour, cutting the travel time to 110 minutes from about 360 minutes.

The line is expected to undergo a pilot run in July before full operation one month later.

Construction on the express rail line started in July 2014.

China's railway network will hit 175,000 km in length by 2025, compared with 127,000 km of operating tracks by the end of 2017. The country is aiming to build 4,000 km of new rail lines this year.
