[citation needed] The first tram engine line that ran between Přívoz and Vítkovice was opened on 18 August 1894 by Brünner Local-Eisenbahn-Gesellschaft (BLEG, Czech: Brněnská společnost místních drah).

The network further expanded in the following years, adding two new lines in 1907: Hulváky-Svinov and Mariánské Hory-Vítkovice[citation needed].

In 1920, BLEG changed name to Společnost moravských místních drah (SMMD) and moved its headquarters to Moravská Ostrava.

Post-World War II, with the industry of the city growing, authorities also developed the public transportation, which included tramways.

[2] Around the same time, it was decided that trams should be the main public transport in the city, as the system was open to be modernised later and could carry a lot of passengers.

Some line sections have also been reconstructed and a new transport terminal at Hranečník was opened in August 2015[citation needed].

In July and August 2020, the speed was increased to 80 km/h between the Třebovice OC and Nová Ves vodárna stops.

In October of the same year, the speed was also increased on the line along Místecká from the Dolní Vítkovice stop to the Jeremenko Colony.
