Brilliant video, thanks! Line 5 was extended east by 1,2 km to Rum Bahnhof three months after this video was recorded; here's my cabview video of this extension: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--tvzIvjgcWA.html . Line 6 will be extended to downtown in December. Construction for line 5 west extension starts next year.
