Public transport in Debrecen, Hungary, is provided by DKV (short for Debreceni Közlekedési Vállalat – Public Transport Company of Debrecen; complete name is DKV Zrt.)
Before mid-2009 two companies provided public transport in the city: trams and trolleybuses were operated by DKV while buses were operated by Hajdú Volán, which provides transport in the rest of Hajdú-Bihar county.
They started providing public transport on 2 October 1884 with horse-drawn and steam-powered trams.
The importance of DKV decreased, and the company lost its leading role in the public transport of Debrecen.
In October 2011 the Spanish firm CAF will be in charge of supply of 18 32-metre Urbos low-floor trams delivered from 2014, for the second tram line which was opened in late February 2014.
Currently, there are over 50 routes (only about 30, if routes with A/Y/I/E or 1 signed bus lines are not counted) and 3 bus types:Volvo Alfa Civis 12,18, Mercedes-Benz Conecto G and ITK Reform 500LE (there only 1 from the last type).
