[1] Although around 30 vehicles are reported to have been refurbished for the reopening of the system, only three were observed in service in May 2016, running on a 1.8 km (1.1 mi) route.

[2] The two routes running northeastwards, lines 1 and 2, operated almost entirely in a segregated busway located in the middle of the wide carriageway (along Damavand Khiyaban), stopping only at purpose-built stops located about every 500 metres, effectively making these routes trolleybus-BRT (but they were not called such).

[3][2] The other three trolleybus routes, lines 3, 4 and 5, ran south from Meydan-e-Emam-Hoseyn along Hefdah-e-Shahrivar (Shahrivar Street) and operated in mixed-traffic.

[9] However, at an unknown date thereafter, Meydan-e-Emam-Hoseyn (Imam Hossein Square) was converted into a pedestrian zone, and the trolleybus service was cut back by about 1 km to Meydan-e-Shohada.

[3] This deprived the trolleybus system of its main role as a fast surface connection to the metro station at Meydan-e-Emam-Hoseyn,[3] causing a decline in ridership that is believed to have been a factor in the c. 2013 closure decision.

[1] The work included modernisation of their front and rear ends and the replacement of the side windows with bonded, tinted ones.

They had also been repainted in a new livery of overall white, except black around the windows, with a "yellow flash" along the side and blue shading on some portions.

[1] Before the 2013 suspension, Tehran's trolleybuses were based at two depots; the two groups of vehicles could be distinguished by their liveries.

[2] Those operating lines 3, 4 and 5 were liveried blue and white (in some cases with yellow highlights) and were based at the southern depot, near Bozorgrah-e-Be'sat.
