The Pyongyang Trolley Bus Factory was inaugurated in April 1959 to produce trolley-buses, buses and other vehicles for passenger traffic in the capital city of Pyongyang, and it has now built up its capacity to mass-produce a wide range of transportation means.

It has modernized essential and core processes and established the integrated manufacturing system to put its production and quality management on a scientific and IT footing, and is continuously reinforcing the production lines and expanding its capacity by means of technical reconstruction. It maintains high standards in quality management by employing advanced measuring devices in performance tests of the products.

At the same time, it encourages its employees to be well versed in modern science and technology and improve their technical knowledge and skills. Thanks to the efforts, the factory has recently developed new-model trolley buses with less power consumption and noise.
