据波兰期刊《Prz.Komun》1986年No.11期介绍,阿根廷、中国、美国、英国、南非等国家,正在以效率为15～20％的蒸汽机车为基础,进行着蒸汽牵引的复兴工作。自1983年起,波兰也开始了同样的工作。主要要求是:新的机车应该按照已掌握的工艺在国产设备上进行生产产:蒸汽机车应用于非电气化线路的货运和客运以及调车作业中;蒸汽机车应有单独的煤水车,以降低机车的轴重;蒸汽机车应采用蒸汽轮机。初步计算证明,第一阶段达到15％的效率是合理的(初始蒸汽压力为1.9MPa,
According to the Polish periodical “Prz. Komun” No.11 in 1986, Argentina, China, the United States, Britain, South Africa and other countries are carrying out steam traction rebuilding based on steam locomotives with an efficiency of 15-20%. Since 1983, Poland has also started the same work. The main requirements are: The new locomotive should be in accordance with the process has been mastered in the production of domestic equipment production: steam locomotives used in non-electrified lines of freight and passenger and shunting operations; steam locomotive should have a separate coal-water truck to reduce Locomotive axle weight; steam locomotive should be used steam turbine. Preliminary calculations show that the first stage to achieve 15% efficiency is reasonable (initial steam pressure of 1.9MPa,
