东北边境铁路（印度）：对运营中的铁路桥梁进行无人机检查，减少列车运行下的人员暴露
印度东北边境铁路（Northeast Frontier Railway）委托外部无人机机构拍摄运营中的铁路桥梁，包括铆接节点和支座。该公司称这减少了在行车状态下对长桥的检查。未给出数量或实测效果，文章日期也前后不一。
| 业主 | Northeast Frontier Railway (NFR), Indian Railways |
| 服务商 | Outsourced drone agency (not named), supervised by NFR bridge engineers |
| 地点 | NFR network, Northeast India (headquarters Maligaon, Guwahati, Assam) |
| 机型 | Not stated (number of drones varied with bridge complexity) |
| 传感器 | RGB still and real-time video |
引入前
桥梁工程师在行车状态下检查长桥，并不安全；跨河桥梁众多，且有难以到达的角落和弯道。
引入无人机后
委托外部机构操作无人机拍摄铆接节点和支座等构件的高分辨率照片和实时视频，由 NFR 桥梁工程师监督。
成果
| 指标 | 数值 | 依据 |
|---|---|---|
| safety | less need for inspectors on long bridges during live traffic (not quantified) | 企业宣称 |
| bridges / time / cost | not reported | 报告值 |
| planned expansion | final location surveys for new lines and train-operation monitoring (the latter under trial) | 目标 |
注意事项与局限
- Short newspaper report based on the railway's chief PRO; no counts, findings or costs.
- The page's publication date (2010) conflicts with its dateline (April 3) and with the history of drone use, so the year is left null; treat timing as uncertain.
- Drones supplemented, not replaced, engineer inspection; a later (2025) NFR programme for submerged bridge parts used underwater robots, not aerial drones, because aerial imaging cannot see below water.
