PASSAGE FIVE

Drones and trains

1.Can a small group of drones guarantee the safety and reliability of railways and, at the same time, help railway operators save billions of euros each year?

2.That is the very likely future of applying today’s “eyes in the sky” technology to making sure that the millions of kilometres of rail tracks and infrastructure worldwide are safe for trains on a 24/7 basis.

3.Drones are already being used to examine high-tension electrical lines.

4.They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points.

5. The more regularly they can be inspected, the more railway safety, reliability and on-time performance will be improved.

6.Costs would be cut and operations would be more efficient across the board.

7.That includes huge savings in maintenance costs and better protection of railway personnel safety.

8. It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance, including sending maintenance staff, often at night, to inspect and repair the rail infrastructure.

9. That can be dangerous work that could be avoided with drones assisting the crews’ efforts.

10.By using the latest technologies, drones could also start providing higher-value services for railways, detecting faults in the rail or switches, before they can cause any safety problems.

11. To perform these tasks, drones for rail don’t need to be flying overhead.

12.Engineers are now working on a new concept: the rail drones of the future.

13.They will be moving on the track ahead of the train, and programmed to run autonomously.

14.Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot.

15.With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time.

无人机与列车

1.一小群无人机能保证铁路的安全和可靠性，同时帮助铁路运营商每年节省数十亿欧元吗?

2.这很可能是应用今天的“空中之眼”技术来确保全球数百万公里的铁路轨道和基础设施全天候安全运行的未来。

3.无人机已经被用来检查高压电线。

4.他们可以做完全相同的事情来检查铁路线和铁路基础设施的其他重要方面，如铁路轨道和转运点的正确位置。

5.检查越定期，铁路的安全性、可靠性和准点率就会越高。

6.成本将被削减，运营将全面提高效率。

7.这包括节省大量的维护成本和更好地保护铁路人员的安全。

8.据计算，仅欧洲铁路每年就花费约200亿欧元用于维护，包括派遣维修人员，经常在夜间检查和维修铁路基础设施。

9.这可能是一项危险的工作，而无人机可以帮助工作人员避免这种危险。

10.通过使用最新技术，无人机也可以开始为铁路提供更高价值的服务，在轨道或开关出现故障之前检测出它们可能造成的任何安全问题。

11.为了完成这些任务，铁路无人机不需要在头顶飞行。

12.工程师们现在正在研究一个新概念:未来的轨道无人机。

13.它们将在列车前方的轨道上移动，并被编程为自动运行。

14.配备先进传感器和人工智能的小型无人机在列车前方飞行，可以像副驾驶一样引导列车。

  15.由于它们有预见未来的能力，它们可以发出任何问题的信号，这样快速行驶的火车就能及时做出反应。
