Since Station Square is the terminus station of the Saburtalo line, the platform and transfer corridor at rush hours may be extremely congested.[4]
Rolling stock
The line is served by the Nadzaladevi (No.1) depot. Currently, 9[citation needed] four-carriage trains are assigned to it. All are the 81-714/717 versions with .5 and .5M modifications. Additional Ema-502M cars were supplied, causing an inconsistency in the cars' design.
Recent developments and potential expansions
The western extension of the line has been frozen for some time before Vazha-Pshavela station opened in the year 2000. It was the first metro station to be opened in independent Georgia. Construction of the State University station (Sakhelmtsipo Universiteti), which dates back to the Soviet era and was suspended for 22 years, was restarted in July 2015 and was completed in October 2017.[2] In perspective, the line might continue to the east.
Older potential development plans included either making the Saburtalo line a circular line continuing in the east towards the direction of Sabcho (Nowadays, Chitaia) Square, Saarbrücken Square, and to
