One of the most ambitious examples of Soviet-era monumental art still standing in Tbilisi, this panoramic mosaic frieze wraps around the former railway depot on Kakheti Highway. Created by Malkhaz Gorgadze, the mosaic features a pronounced relief structure — its figures have three-dimensional form rather than being rendered flat, which was unusual for the genre.

The composition celebrates technological progress in the spirit of the era: the sun dominates the center, surrounded by imagery of rockets, waves, stars, a hot air balloon, and geometric forms — a visual hymn to human mastery over nature and industry. The title, The Speed of Electricity, is a direct nod to the electrification of Soviet railways, a prestige project of the USSR and a point of particular pride in the Caucasus. On August 16, 1932, for the first time in the USSR, the first electric traction train ran in Georgia — on the Surami pass — making the Georgian railway a pioneer of Soviet electrification
