Locomotives of the same design operated in Yugoslavia as JŽ class 11.[1]
Fifteen were supplied to North Korea as war aid during the Korean War; these kept their MÁV running numbers (424.006 through 424.020) in Korean State Railway service.[2] These went to Záhony on the Hungarian–Soviet border under their own power, where they were disassembled and shipped via the USSR to China; in China they were reassembled and delivered to North Korea under their own power.[3]
