6. Abstract
: This paper suggests the traction capability and traction factor of a 8500-electric locomotive for operation in North Korea. The traction factor can be calculated by dividing the towable weight of total freight by the normalized weight (43.5ton) of freight. The 18 speed levels have their own traction factors in South Korea. This means that the traction factor is determined by the maximum traction force of electric locomotives. However, in North Korea, railway substations should be considered to define traction factor because the capability of railway substations in North Korea is smaller than that of the 8500-electric locomotive. In this paper, the traction force of the 8500-electric locomotive, the railway resistance, the gradient of rail, and the capability (2100kVA × 2, 2100kVA) of substations are considered to define the traction factor of the 8500-electric locomotive for operation in North Korea.
