The Yunchaojian River Tunnel, the only tunnel in the Beijing Municipal Administrative Center section of the Beijing-Tangshan Intercity Railway, has been successfully completed, marking the full completion of all tunnels along the Beijing-Tangshan Intercity Railway.

The Beijing-Tangshan Intercity Railway is a crucial high-speed intercity railway serving the Bohai Rim and the Beijing-Tianjin-Hebei region. Once the Beijing Municipal Administrative Center section is finished, trains from Tangshan Station will provide direct service to the Beijing Municipal Administrative Center Station.
