Tashaocun tunnel was cut through on the morning of January 9th, which marks the completion of all tunnels on Baoji-Lanzhou passenger dedicated railway and lays solid foundation for the timely opening of the line as scheduled.

　　With a total length of 401km and a designed speed of 250km/h, Baoji-Lanzhou PDL originates from Baoji, Shaanxi province, and terminates at Lanzhou, Gansu province. There are as many as 12 tunnels with a total length of 39.9km on the 45.9km-long Shaanxi section,including the 4926m Tashaocun tunnel. Given that, the project faces great pressure in terms of engineering difficulties and tight schedule.
