Metro is an environmental-friendly, safe, fast and comfortable transport of future to carry passengers in cities. The name "Metropolitan" comes from the French work "Metropolitain", meaning an underground city. In just about 25-30 minutes, any resident or guest of Tbilisi can get from one end of Tbilisi to the other in a safe and comfortably way. Metropolitan is open for passengers from 6:00 a.m. to 12 p.m. Metropolitan has 22 stations. Besides, Metropolitan is connected to the city by the station exists basically located in the underground crossings of streets.

For the time of its existence, Metropolitan has carried over 4 billion eight hundred thousand passengers. It all started this way:

On September 29, 1951, the Council of Ministers of the former Soviet Union made a resolution on constructing Metropolitan in Tbilisi. Tbilisi Metro Construction Department was set up in 1952. The year 1953 saw the commencement in the construction of the first pit and intermediary tunnels. The Directorate of Metropolitan under construction was set up in 1962 and the Metropolitan Department with the relevant structural units – on February 8, 1965.

January 11, 1996 was the day, on which the first line section of 6,3 km was launched to cover the following six stations: Didube, Electrodepo, October (now Nadzaladevi), Station Square, Marjanishvili and Rustaveli.

The double-track traffic was organized in March 1967, with the possibility for trains to turn around in Didube Station. In November the same year, after the line had been extended by 4 km down to 300 Aragveli Station, it was possible to turn the trains around at the other end of the track. However, it was only after completion of the intermediary tunnel called Nadzaladevi that the double-track traffic could be opened across the entire route. 

The launching of a 2,5-km section in May 1971 down to Samgori Station marked the end of the first line of Metropolitan of 11 stations, with the total length of 12,3 km.

September 1979 was when the other Metro line of 5,8 km in length was launched to link Station Square to Saburtalo District.

According to the original plan, the other line was thought to be a branch of the first line but right in the construction completion phase a decision was made to build the other interchange station called Station Square – 2 that at the beginning would not have an independent aboveground exit.

The month of November 1985 saw a concurrent launching of two sections:  one  - 3,4 km from Didube Station to Marjanishvili Station and the other – 2,0 km from Samgori Station to Varketili Station. Akhmeteli Theatre Station was added only in January 1989.

Another section called Delisi-Vazha-Pshavela of 1,2 km single-track traffic was launched in 2002.

To hedge against interruptions in power supply and ensure the operation of Metropolitan as a strategic facility, Metropolitan has 2 diesel-powered stations of 6 power units with the combined capacity of 7,8 000 kW.

The Metropolitan tracks are mostly underground with the exception of 3-km aboveground section from Didube to Electrodepo.

The throughput capacity and equipments of Metropolitan are designed on 5-carriage 36 couples of trains per hour. At present, 36 trains run on the tracks to carry 300 000 passengers a day.
