Britain’s railways have faced a string of(一连串；一系列) heat-related problems this summer, including a derailment(脱轨；出轨) near Lewes in East Sussex two weeks ago that injured 30 people, and another the next day when the rear(后部的；后面的) carriage(（火车）车厢)s of a Greater Anglia train derailed “in an upright(直立的；垂直的) position” at Wickford railway station in Essex, with no reported injuries.
今年夏天，英国铁路面临一连串与高温相关的问题，包括两周前在东萨塞克斯郡刘易斯附近发生的一起脱轨事故，造成30人受伤；次日，一列大安格利亚列车的后部车厢在埃塞克斯郡威克福德火车站“以直立姿态”脱轨，据报道无人受伤。
The problems came during one of the hottest and driest summers on record(有记录以来的), with a series of heatwaves, and drought(干旱；旱灾) declared across large parts of England and Wales. Britain’s railways, built for a cooler, wetter climate, have been put under pressure(使承受压力). Network Rail said the summer had “presented exceptional(异常的；杰出的) challenges to the railway”.
这些问题发生在有记录以来最炎热、最干旱的夏季之一，期间出现了一系列热浪，英格兰和威尔士大部分地区宣布干旱。英国铁路是为更凉爽、更湿润的气候而建的，如今已承受压力。英国铁路网公司表示，这个夏天“给铁路带来了非同寻常的挑战”。
Here’s what we know about how heat affects the rail network and what can be done to tackle it.(以下是我们所了解的关于高温如何影响铁路网以及如何应对的情况。)
