PFC Lokomotiv Plovdiv (), commonly known as Loko Plovdiv, is a Bulgarian professional football club based in Plovdiv. Lokomotiv's home ground is the Lokomotiv Stadium which is situated in Lauta Park and has a capacity of 14,000 spectators. Founded on 25 July 1926, Lokomotiv is one of the most popular teams in Bulgaria and currently competes in the top-flight First League, which they have won once (in 2004). Lokomotiv Plovdiv has won also 2 Bulgarian Cups, 2 Bulgarian Supercups and 1 Cup of the Soviet Army. The biggest success of the club in Europe is reaching the third round of the Inter-Cities Fairs Cup in 1965, after narrowly losing to the Italian Juventus in a play-off match. Lokomotiv have a fierce local rivalry with fellow Plovdiv-based team Botev Plovdiv. Matches between the two sides are known as the Plovdiv derby. History Throughout the club's history, it has undergone a number of complex reorganisations. These were in part due to the political environment in Bulgaria during the communist period (1944-1989) which led to enforced changes in the nature of sporting clubs throughout the country in order to follow the "Soviet model". For PFC Lokomotiv Plovdiv, these changes led to the merger of two separate existing teams, different in nature, which in turn has led to misinterpretations of the history of the teams. In order to understand the origin of the contemporary team, Lokomotiv's history can be divided into two major branches – one defined largely by its followers (Sportclub Plovdiv), and the other by its functional characteristics, association with the railway, and funding as a labour union team (ZSK Plovdiv). Roots of the Club (until 1944) Sportclub Plovdiv In the spring of 1922, the sport club Karadzha was founded when several casual amateur football teams in one of the districts of Plovdiv consolidated so the players could compete in the Championship of Plovdiv. Two years later, in 1924, another sport club called Atletik was formed in the same district. On 25 July 1926 Karadzha and Atletik merged to form Sportclub. The team chose white, black and red as the colours for their kits and crest. Several years later, the year of establishment (1926) was added to the crest. Lokomotiv Plovdiv still uses the same colours, while their full name (Professional Football Club Lokomotiv 1926 Plovdiv) shows the club's beginnings as the same year in which Sportclub was founded.
