It is already no trams and trolleybuses in Tbilisi. I have found a picture of 3-car body tram built in 1962.
The Tbilisi is a three-car body-section, for-axle, uni-directional, high-floor tram developed by Tbilisi’s tram & trolleybus commission. The design was introduced in 1959, and the first 4 car was completed in 1960. These trams was completed in Tbilisi’s tram repairing works.
The Tbilisi tram had two fixed bogies, but middle section was hanging of the neighbouring sections and jointed through rotatable capsules.
