Passenger & freight cars
As far as passenger cars go, the TT-Modell sleeper and the Y sleeper can be used to model DPRK sleepers used on the Pyongyang-Beijing and Pyongyang-Moscow trains; domestically, however, they use primarily cars of the Chinese YZ22 design (which exists in HO) and North Korean design - which don't exist in any scale, but Russian domestic stock can be used as satisfactory stand-ins.
As far as freight cars go, of existing TT models, only the Russian tank car from Peresvet, and one or two others can be used in modelling DPRK equipment, as most of their equipment is, again, either locally produced or of Chinese design/production (some of the Chinese equipment is available in 1:87 as well). Some North American equipment can be used as close stand-ins too for old colonial-era equipment still in use, such as the Gold Coast Fowler car.
Geumseong 8002 - DPRK-built copy of M62. Two are known - 8001 in regular service, and 8002 which has been at the Museum of the Three Revolutions since it was built.
