大同机车工厂研制的前进二型煤气蒸汽机车已经完成装车工作,于1986年9月22日在工厂举行了剪彩仪式。前进二型机车是在原前进型机车煤水车上装设煤气发生炉,炉内生成的煤气经过煤气道输送至机车火箱内燃烧。它具有以下特点:燃烧效率高,降低煤耗量,不冒黑烟,改善环境污染;降低排烟损失,提高锅炉效率,据计算,机车轮周功率3000马力,机车总效率提高25％比烧原煤操作简便、清洁,大大改善了劳动条件。前进二型机车在厂内试运线上经过两次试运,最高速度达68km/h,所有运行设备正常。于1986年10月8日单机挂守车一辆,在北同蒲线大同至北周庄间进行了单线本线试运行,由于线路限速,最高速度达70km/h,往返运行152km,运行正常,安全返回大同工厂。
Datong Locomotive Works forward two type gas steam locomotive has been completed loading work, on September 22, 1986 held a ribbon-cutting ceremony at the factory. Forward two locomotives is installed in the original forward locomotive coal-water generating gas furnace, the gas generated in the furnace through the gas pipeline to the fire locomotive combustion. It has the following characteristics: high combustion efficiency, reducing coal consumption, non-black smoke, improve environmental pollution; reduce exhaust losses and improve boiler efficiency, according to the calculation, the locomotive wheel power 3000 horsepower, locomotive total efficiency increased 25% Easy to operate, clean, greatly improving the working conditions. Forward two locomotives in the factory trial line after two trial run, the maximum speed of 68km / h, all running equipment is normal. On October 8, 1986, a single hang on a car in the North with the bus line from Datong to Bei Zhouzhuang a single line of this line of trial operation, due to the line speed limit, the maximum speed of 70km / h, run back and forth 152km, the normal operation , Safe to return to Datong factory.
