There is no news about engine rolling except the actual commercial operations that would begin late in November 2016. As long as the work progress is considered, 99% is finished and the track was joined to the existing dead end rail (dead end of a railroad with buffer) near the railway station, the other 1% is the clippings that hold the track are yet to be installed along a kilometer long section near the station. Moreover, renovation works are going on at the station such as installation of lifts. I think they may roll the engine in July this year.
