Notes on Pyongyang Trolleybuses

The bodies of trolley buses were made manually since, apparently, at the Pyongyang trolley bus factory there were no hydraulic presses large enough. The necessary shaping of sheet metal was achieved by hammering, and thus the surface was covered with dents and holes. Electricity wiring was tacked to trolley bus ceiling were extended directly on the ceiling while its plywood plates often hung and flapped above passengers' heads. It should be said, however, that the backward technologies were partly compensated for by diligent and persistent labour. For example, these badly made trolley buses were kept spotlessly clean -- sharp contrast to the then Soviet ones, which were technically much more advanced, but always dirty.
