Note, this photo clearly shows that the east-west move via the city's main tramway thoroughfare Strada Basarabiei was possible (two trams in this photo), while the west-east move in the opposite direction was not, see the partially dismantled track. The latter move was completed via an indirect route through Strada Tecuci:

The entire junction at Piața Energiei will later be rebuilt into a tramway rotary with moves possible in all directions of travel. See details on rather complicated arrangement of tramway moves around Piața Energiei posted here:

Обратите внимание, на этой фотографии чётко видно, что движение с востока на запад по главной трамвайной магистрали города Strada Basarabiei было возможно (см. оба трамвая в кадре), а вот движение с запада на восток в противоположном направлении — было невозможно, см. частично разобранный путь. С запада на восток трамваи шли в сложный объезд через Strada Tecuci:

Узел на Piața Energiei позже будет полностью перестроен в трамвайную круговую развязку в стиле Екатеринбурга, с возможностью движения во всех направлениях. Подробности по сложной организации трамвайного движения вокруг Piața Energiei см. здесь:

The Tatra T4D tram was actually on "Cursă convenție" - This means a special route for the steelworks, and it could only be used by the workers of the steelworks.
Route 6 was known as 6b back then and it was between steelworks and Piața Centrală. (Later it became 6 and had the route between Bazinul Nou and steelworks, while Piața Centrală - steelworks became route 2, but for a short period of time).
This kind of routes (E.g. 1, 3, 6, 43...) had a special timetable, in order to transport workers to and from steelworks, but could also be used by public.
The Tatra KT4D 0098 was actually not in service. It was going back to the depot after it served route 36.
