We spent the whole day in Pyongyang and visited:
Mansudae Fountain Park
Victorious Fatherland Liberation War Museum
Juche Tower
Pyongyang Metro
Mangyongdae Children's Palace
Pyongyang Circus
Cost of a five-day tour to the DPRK: $1378.
The five-day tour included 4 flights (Vladivostok - Pyongyang - Orang - Pyongyang - Vladivostok), accommodation, meals, excursion program (Pyongyang and Chilbo), visa, insurance. Some entertainment is paid for additionally ($20 - circus, $7 boat ride, etc.).
The train cars are most likely old Berlin metro cars which were sold to North Korea.
Cited in the video. They’re German constructions probably imported back before the collapse of the USSR.
