Work on the 8.8km Sanleng Mount Tunnel started on 28 February to spearhead the Beijing-Shenyang railway project, according to a statement from the provincial transportation department.
The tunnel will stretch from the city of Beipiao to Fuxin Mongolia Autonomous County. It will be completed within 33 months, the statement said.
The 709km Beijing-Shenyang railway project is expected to be finished within five years, after a total investment of CNY 124.5bn (USD 20.3bn).
The railway, designed for a speed of 350km per hour, will halve the travel time between the two cities to 2.5 hours, according to the provincial transportation department.
