 The new route's length, , is almost identical to that of line K, but it shares half of its length with line K. Line Q's other half (along Avenida Francia) lacks any overhead wires, and to serve it, SEMTUR placed an order in March 2016 with the Russian manufacturer Trolza for 12 "Megapolis"-model trolleybuses capable of operating in regular service away from the trolleybus wires part of the time.The choice of manufacturer and model was influenced by the fact that another Argentian trolleybus system, the Córdoba system, had recently purchased the same type of trolleybuses; they entered service in February 2016.Although new line Q did not require any new overhead wires, the project did require the purchase and installation of four additional traction substations.
