Beijing, Sep 16 (PTI) Nine construction workers were rescued today after they were trapped for two days in a collapsed railway tunnel in southwest China’s Yunnan province.

Rescuers managed to dig a passageway to reach the workers. The first worker was rescued at about 12:40 pm and eight others were pulled out minutes later.

All the workers are in a stable condition, state-run Xinhua news agency reported.

The tunnel in the Xishuangbanna Dai Autonomous Prefecture, where they were working, collapsed on Thursday.

After digging a small opening through the rubble, rescuers managed to contact the workers with the help of a thin pipe and confirmed that all them were alive.

They also installed a mobile phone signal amplifier to help them keep in contact.

Later, the workers were offered food three times, the report said.

More than 230 workers were involved in the rescue operation by excavating small tunnels or larger passageways in four directions.

The tunnel is part of a railway that connects Yuxi and Mohan in Yunnan.
