DKV
The company was founded in 1883 under the name Debrecen Local Tramway Company. They started providing public transport on October 2, 1884 with horse-drawn and steam-powered trams. The first electric tram started operating in 1911. From 1906 the town of Hajdúsámson and later, the town of Nyírbátor were connected to Debrecen by municipal railway, also operated by the same company.
By the 1940s there were already ten tram lines. On June 2, 1944 the city was bombed, and the tramway system was seriously damaged. They were repaired by 1947, and seven tram lines were serving the city until the 1970s, which brought a decrease in the popularity of trams. Tramways were demolished all over the country, the role of trams was taken over by buses. Today Debrecen is one of only four Hungarian cities to have a tram line, but even here only one line survived, the rest were demolished. The importance of DKV decreased, the company lost its leading role in the public transport of Debrecen.
Trolleybuses started operating in 1985, several of them serves on lines which used to be tram lines before the 1970s.
The company became state property on July 15, 1950. Today it is city property.
