A |     Jet engine maker Rolls-Royce said Tuesday it's cutting up to 2,500 jobs globally as part of a corporate overhaul that its new CEO is carrying out. The aerospace company was hit hard by the COVID-19 pandemic that decimated demand for air travel. Tufan Erginbilgic, who took over as chief executive in January, said the layoffs are aimed at making Rolls-Royce “more streamlined and efficient." Rolls-Royce, based in Derby, central England, didn't disclose where jobs will be cut, but around half of its 42,000-person workforce is based in the United Kingdom.The cuts will remove duplication and bring cost efficiencies in the latest stage of its “multi-year transformation," the company said. “We are building a Rolls-Royce that is fit for the future," Erginbilgic said. The company slashed 9,000 jobs globally in 2020 as it grappled with the collapse of air travel during the pandemic.The new turnaround plan also includes creating a new company-wide procurement division that can take advantage of Rolls-Royce's size to cut costs and reduce supply chain delays.。    　　北京8月25日电 (记者 徐婧)北京市重大项目办和京投轨道公司25日介绍，北京轨道交通22号线(红庙—平谷)当天正式开启空载试运行。该线是首条横跨京冀两地的城市轨道交通线路，预计今年底基本具备开通条件。　　22号线(红庙—平谷)西起北京朝阳红庙，东至平谷新城，全长约79.1公里，共设车站20座(北京段15座、河北段5座)。线路横跨北京朝阳、通州、平谷以及河北三河，串联起CBD核心区、北京城市副中心、河北燕郊、平谷新城等重点功能区。项目建成后，将实现河北省三河市与北京城市轨道交通网的“无缝衔接”，便利跨省通勤，显著增强北京城市副中心对北三县的辐射带动作用，以交通先行引导功能疏解与产业协同。北京轨道交通22号线(平谷线)线路示意图。　北京市重大项目办供图　　北京市重大项目办相关负责人介绍，22号线是区域交通互联互通的“大动脉”。开通后，线路将在红庙站与14号线、管庄站与1号线(八通线)、北关站与6号线、城市副中心站与6号线及京唐城际铁路实现高效换乘。该线速度优势明显，高架段最高时速达160公里，地下段达120公里，实现了“高铁速度”与“地铁密度”的结合。届时，从河北燕郊镇到北京城市副中心最快仅需9分钟，到北京CBD核心区红庙站最快约28分钟。　　京投轨道公司相关负责人介绍，22号线建设全过程贯穿科技创新。在智能建造方面，采用百米长轨工厂化预制与机械化铺设，同时运用高铁先进的精密测量、线路精调、动态测试等技术，实现线路的高平顺性；自主研发智能盾构施工体系，实现掘进全过程智能操控；平房停车场配套建设光伏发电项目，打造绿色施工新标杆。在智慧运营方面，建设了北京首条全面面向乘客服务的智能视频分析平台，实现客流监测、安全预警与乘客服务的深度融合。　　按照计划，本次空载试运行将分两个阶段实施。第一阶段重点开展车辆、信号、通信等八大系统的综合联调与功能测试，第二阶段将严格按照运行图开展“跑图”试运行，对列车正点率、运行图兑现率等关键指标进行全方位验证，确保线路各项运行指标达到初期运营前安全评估标准。
