Police investigating an attack on a London tube train last week have arrested a teenage boy.

调查伦敦上周某地下铁道列车遭受袭击的警察逮捕了一名少年。

EARLY in 1959 passengers on a London tube train defied an announcer's instruction to “all change”, before being thrown off by police.

早在1959年，伦敦地铁广播员下令所有乘客遵循指令，没有接受指令的乘客们就被警察赶下了地铁。

The number of Londoners increased by 12% from 7.3m in 2001 to 8.2m in 2011, and Tube trains are broiling and overcrowded.

从2001年的730万到2011年的820万，伦敦人口增长了12%，地铁变得又热又挤。

We all have stories of commuting nightmares – a tube train stuck in a tunnel or a bus journey where people are packed in like sardines.

我们都有通勤噩梦的故事——地铁卡在隧道里，或者乘坐公共汽车，人们像沙丁鱼一样挤在一起。

This induced paranoia: Mr McCrum took to keeping his notebooks in a safe with six-inch steel walls, and jumping off Tube trains just as the doors were closing, in case he was being tailed.

这引发了偏执狂：McCrum 先生把他的笔记本放在一个有 6 英寸钢壁的保险箱里，并在门关闭时跳下地铁， 以防他被尾随。
