On 18 September 1943, the first trolleybus drove in Gdynia (German in that time: Gotenhafen), running from the offices of the city to Hauptbahnhof station.

Initially, ten Henschel trolleybuses serviced the network, fitted with AEG electric systems.

The bodies of the trolleybuses were created by Danziger Waggonfabrik (Polish: Gdańska Fabryka Wagonów, Gdańsk Wagon Factory).

An action to take the trolleybus wreckage from the streets to the depot near ulica Derdowskiego commenced.

The electrical substations at Redłowo, Dworzec and Grabówek, which powered the previous trolleybus network, were secured from further destruction.

On 19 March 1946, the trolleybus line from the depot near ulica Derdowskiego to the city offices was opened, and a loop was established.

In 1949, MPK Wrocław gave Gdynia 8 Tallero trolleybuses that were abandoned by Germans and not activated.

On 29 October 1949, a new line numbered 24 was opened to Oksywie, with a loop by Dowództwo Marynarki Wojennej.

On 23 May 1964, line 24 acquired an expansion, numbered 28, consisting of a branching from ulica Bosmańska in Obłuże through Oksywie to the loop by Dowództwo Marynarki Wojennej.

The line 24 loop was moved to near the Gdynia Port Oksywie railway station.

From 1971, there was a lack of new trolleybuses, caused partially by failure to renew contracts with Czechoslovakia.

As a result of the lack of necessary new deliveries, the Wojewódzkie Przedsiębiorstwo Komunikacyjne Gdynia-Gdańsk (WPKGG) proposed the development of a prototype for a national trolleybus based upon the Jelcz-Berliet PR110U bus with electrical equipment by ELTA in Łódź and traction motors by Škoda.

From 1974 to 1976, cooperation was established among the Polish Federation of Engineering Associations, WPKGG, and Jelczański Zakład Samochodowy, leading to the development of two trolleybus prototypes based upon the Jelcz PR110U.

It was also decided to maintain and modernise the wires along ulica Wielkopolska, with an expansion to Wielki Kack.

In the 1990s, after the transition to a free market economy, MZK began to encounter financial problems caused by vehicle aging.

As a result of the implemented changes, the public opinion about the trolleybus network improved.

At the time of the creation of PKT, the public opinion of the trolleybus network was poor, mainly because of the organisation of traffic in the city.

PKT began the process of replacing older vehicles and modernising the network, which eliminated many of the previous problems.

With Poland in the European Union, it became possible to receive funds for rebuilding and modernising the trolleybus network or to purchase more vehicles.

[7] Due to the elongated shape of the city and the terrain conditions, the trolleybus network was planned along main streets.
