创造一种安全,更有弹性的铁路,现在和将来更加有弹性。
天气如何影响我们的资产?
天气是在短时间内观察到的,例如强烈或长时间的降雨,散热,冷扣,飓风和雪。例如,过度的降雨可能会泛滥我们的基础设施或破坏线条,使土方工程易于徘徊。
下面的图像显示了天气如何影响我们的资产,损害我们的基础架构,并导致延误。解释了对这些延迟的解释亚搏彩票软件官网网络铁路网站。
How does weather impact the railway?
The main impacts of weather on the railway are: costs, poor performance (measured by Public Performance Measure (PPM), and safety risks.
在过去的12年中,铁路网络中PPM成就平均降低了平均2-3%。极端天气的影响可能更为显着,年龄从一年增加到大的变化。

由于延误和取消,天气影响每年为每年50英镑50英镑。如果包括铁路和经济的更广泛的成本(例如错过的目标,维修和社会经济影响),这一上升至200亿英镑。
从安全视角,幸运的是,我们近年来天气事件的影响造成了任何严重的事故。然而,2016年9月在2016年9月在2015年12月在Lamington的桥梁冲浪的土地上是提醒严重后果的潜力。
The figure below shows the delays associated with weather-related incidents across the network for the past decade. Further detail on delays can be found on the National periodic reports page and by Route, in the form of periodic reports using the links in the side-bar.

从2012到2017年到2017年频繁和严重的洪水是影响火车延误的主要天气因素,然而,在近年来的模式发生了变化。2017-2018年度从雪地看到了一个特别大量的延迟分钟,从2018-2019开始了一个鲜明的对比,从热量中看到许多延迟分钟。S8延迟分钟的越来越多地关注关键基础设施的需求,以适应当前和未来的天气极端。
In response, the government and our regulators are seeking assurance that we understand the risks of our changing climate and are acting to enhance resilience and adapt to the impacts, both now and in the future. In 2015 we produced an overarching Climate Change Adaptation Report (available in the side-bar) for Defra which summarised our progress towards understanding the potential impacts of climate change on the performance and safety of the rail network, and actions taken to increase resilience. We will be producing our third Adaptation Report for Defra in 2021.
Climate change
气候变化将导致现有的天气模式转变,改变事件的严重程度,频率和影响。维持和改善,我们的弹性将变得越来越具有挑战性,因为这些变化放大了资产失败对不可接受的水平的风险和影响。这种转变将意味着我们的历史记录,不能依赖于我们未来的业务和投资决策的历史记录。我们正在努力提高对风险变化的理解,以便我们可以计划何时,以及如何调整我们的回答,以应对新的正常情况。

我们在做什么来管理风险?
In 2017 we produced a天气弹性和气候变化适应(WRCCA) Strategywhich aims to deliver a railway that is safe and resilient to the effects of weather, now and in the future. It lays out the key principles and actions necessary to get to the position where weather and climate risk management is embedded in decision making processes across the business.
By embedding future weather consideration into business planning and asset management processes we will increase the resilience of the railway; reducing weather-event related safety, performance and cost impacts.
在路线中交付WRCCA操作是通过单独的路由WRCCA计划,目前的计划可以访问侧栏的路由特定页面。这些是2014年首次出版的,更新版本将于2019年发布,以反映英国气候变化预测的新分析,控制期投资计划和更新。
Underpinning all our work is analysis of operational weather impact data to improve our understanding of our current and future risks to inform our resilience planning and responses. For further information follow the Route links in the sidebar.
