In a Japanese book entitled Railways to Save the Earth, the opinion is expressed that trains really have far more advantages than motor vehicles. Not only do the tracks take up less space than roads and blend in better visually with their surroundings--trains also save oil and produce far less emissions and noise pollution than motor vehicles.
日本有一本書叫《鐵道救地球》，認為火車與汽車相比之下，還真是好處多多，不但軌道佔據的空間小，視覺上與空間比較協調，還能節約石油，它的廢氣及噪音汙染也都小於汽車。
