Sofia Normal gauge entry to depo Krasna Polyana. August 2017.
From the endloop of line 22, the normal gauge track enters the depo straight. In summer 2017, several T4D-M were kept here to operate line 22A (due to rebuilding on bul. Kniaz Alexandar Donukov). Photo by M.Koblischka #m.koblischka@mx.uni-saarland.de
