当年“火车一响,黄金万两”的吹嘘和当今“要想富,先修路”的宣传是一个道理。火车是人类利用化石能源运输的典例,使人们的出行更加便捷,推动了交通工具的进步。火车畅通物流,振兴经济,使社会进步和发展得到了腾飞。当然,过去火车的煤烟和噪声也对环境造成了一定的危害。 At that time, the propaganda of “Train Rings, Gold Wanliang” and today’s “wanting to be rich and building roads first” is a truth. Trains are the typical example of the human use of fossil energy transportation, making people travel more convenient and promote the progress of transport. The smooth flow of trains, revitalization of the economy, so that social progress and development have been taken off. Of course, the soot and noise of trains in the past also caused some damage to the environment.
