Drones are already being used to examine high tension electrical lines. 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. The more regularly they can be inspected, the more railway safety, reliability and on 　time performance will be improved. Costs would be cut and operations would be more effi cient（高效）across the board. That includes huge savings in maintenance costs and better protection of railway personnel safety. 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.
