为什么日本有这么好的铁路
日本的铁路是世界上最好的。其他国家可以复制其公式。 日本是电车之国。日本 28% 的旅客公里数是通过铁路运输的，这一比例高于其他发达国家。法国达到了 10%，德国达到了 6.4%，而美国仅为 0.25%。在日本旅行乘坐铁路的可能性比在美国旅行的可能性高一百倍以上。 日本庞大的铁路网络由数十家公司划分，几乎全部都是私营公司。其中最大的铁路公司东日本旅客铁道 (JR East) 的载客量超过了除中国和印度以外的所有国家的整个铁路系统。每年，JR东日本运送的旅客数量是整个英国铁路系统的四倍，尽管它的轨道公里数较少，服务的人数减少了约一千万，并且与其他八家公司竞争。日本铁路系统的营业利润很高，但获得的公共补贴却远低于欧美铁路。 订阅 100 美元即可每年收到六期精美期刊。
