The Parma trolleybus system (Italian: "Rete filoviaria di Parma" ) forms part of the public transport network of the city and "comune" of Parma, in the region of Emilia-Romagna, northern Italy. In operation since 1953, the system presently comprises four urban routes. Using only the above description and what you know about the world, "The trolleybus system has over 2 urban routes" is definitely correct, incorrect, or inconclusive?
