Opened in December 1955, the system had waxed and waned in size over time. Template:As of the beginning of, it was made up of only one route. There are current disputes between the operator and the municipality regarding the validity of the trolleybus contract. Gradski Transport Plovdiv is still the operator of this type of transport, despite the numerous infractions of the contract since 2010. Due to the fact that the operator is a private company, in October 2012 the city lost the opportunity to acquire 65 mln lv EU funding for purchasing approximately 100 brand-new trolleybuses.The system was officially closed on 1 October 2012 although some trolleybuses continued operation for a few more weeks.Currently there is no trolleybus movement and the municipality has issued an order for dismantling the overhead network.
