In Aug. 2020, Moscow’s city council decided to discontinue the trolleybus service, heralding a major transformation of the city’s public transport system. The service, once seen as the transit system of the future, has been a prominent feature of the Soviet or Russian capital since 1933 — nearly 90 years.

But there’s a surprising North Korea connection here, too: The trolleybus has been the backbone of Pyongyang and other major cities’ public transportation systems since the 1960s.
