Sofia bul. Bulgaria at the crossing with bul. Petko Y. Todorov. October 2017.
Here, ul. Kjustendil (running parallel to bul. Bulgaria) is closed, which is normally used by trolley buses. A PESA Swing is waiting to continue towards NDK (line 7). Photo by M.Koblischka #m.koblischka@mx.uni-saarland.de
