"As component manufacturing for narrow-gauge railways has basically been discontinued domestically, and the drivers and passengers are reaching their senior years, coupled with the tough work conditions and low salaries, it is difficult to find young successors and continue to operate. We could barely keep the line running," says Li Zhenjun, general manager of the Supply and Marketing Company of Martian Mining Co, Ltd. "A few years ago, someone proposed to dismantle the narrow-gauge railway, and we strongly opposed it. It was heart wrenching to watch many of our steam locomotives being sold."
