Second Warsaw subway line to open in mid December

The already finished central part of the second subway line in Warsaw will be opened on December 14, Polish Radio reports. Construction on the line was completed at the end of September. The underground railway needs to conform to safety requirements and the technical approvals are taking longer than planned, city hall spokesperson Bartosz Milczarczy told the radio. The second line connects the banks of the Vistula. The central part has seven stations. It is set to be extended by three stations in each direction by 2019.
