On December 1 last year, a new tram corridor passing through the Old City Harbour (Vanasadam) was opened, with tram line 2 being rerouted to this track. Data shows that it is now the most popular tram line in Tallinn, with approximately 400,000 rides recorded in January.

Deputy Mayor of Tallinn, Kristjan Järvan, explained that several major changes are planned for the city's tram network in the coming years. “The construction of new routes to Liivalaia Street and Pelgurand will improve the efficiency and reliability of tram traffic. In the future, tram line 2 will connect Pelgurand, Balti jaam station, the central bus station, the Rail Baltic terminal, and the airport, providing better mobility options for both residents and visitors. There are also plans to reroute tram line 3 via Liivalaia Street to further enhance urban connections,” said Järvan.

In January, approximately 400,000 rides were made on tram line 2. The most used stop on the new Old City Harbour route is A. Laikmaa, whose popularity has helped reduce congestion on the narrow waiting platform at Hobujaama stop. Previously, Hobujaama was a bottleneck for tram traffic, limiting the possibility of increasing tram frequency. The new Old City Harbour tramway has eased pressure on Hobujaama, making it possible to plan for more frequent departures in the future.

On weekdays, around 6,000 passengers use the stops along the Old City Harbour tramway section. During the week, approximately 300–400 people travel to the port using tram line 2, with a similar number departing from the port. On weekends, this number ranges between 350 and 450.

The next most popular tram lines are lines 1 and 4, with 315,000 and 313,000 rides recorded in January, respectively. Tram line 3 had approximately 110,000 rides, while tram line 5 recorded around 116,000 rides. Notably, tram line 5 achieved a similar number of rides as tram line 3, despite having significantly fewer departures.

Since passenger counting sensors are only installed in newer trams (PESA, CAF), the data has been partially extrapolated, as older KT6 trams are still in limited operation on some routes.
