The AGP Poland consortium, which comprises Astaldi, Italy; Gulermak, Turkey; and PBDIM, Poland, says that all construction works have been completed with the exception of trackwork at one of the seven stations.

The 6.5km east-west line will link Dworzec Wileński with Rondo Daszyńskiego and runs completely underground for its entire length. Services will be operated by a fleet of 20 six-car Inspiro metro trains being supplied by a consortium of Siemens and Newag.

The line is due to be handed over on September 30 for the start of test operation and certification for passenger use.
