Since 1961, Pyongyang Trolleybus Works has produced Chollima 1, 2, 9.11, 9.25, 70, 72, 74 and 84, Chongnyon, Chongnyonjunwi, Ikarus 260T and Chollima 032 trolleybuses; the Chollima 962, 90/903, Ikarus 280T and Sonyon articulated trolleybuses, Pyongyang 9.25 buses, Kwangboksonyon articulated buses and Chollima mini-buses.
However, during the 1950s most of the personal and infrastructure of the aircraft factory were relocated to SOKO, and since then Ikarus has focused completelly on bus production, first under licence originally of Sauer and MAN designs, and later of company's own designs.
Capital Logistics also operated Connections branded Optare Excels on local Uxbridge - Heathrow route U3 and the ex-Green Line route 726 gained from London Coaches, replacing the Ikarus 480-bodied DAF SB220s initially used.
From 1954 onwards, Ikarus commenced bus production, originally of Sauer and MAN designs under licence, but eventually the company's own designs.
Ikarus provided body shells (without doors, windows, seats, engine) for Orion Bus Industries contracts to supply Toronto and Ottawa transit systems with articulated buses in late 1986-1987.
The new prototype is named Ikarus IO (Coastal Reconnaissance) and the first test flight took place on the Danube at Novi Sad, September 1926th year.
