4 ms·BNSF Railway Evaluating Drones in New Mexico12 points by kposehn 11y agomodeless 11y agoCaltrain needs these.ant6n 11y agoI dunno, it seems it would be easier to inspect rail lines using rail drones rather than aerial drones.cpitman 11y agoI'm not sure that is true. Anything on the rails has to inter-operate with rail traffic and control systems. A drone can inspect the track regardless of rail traffic.jlarocco 11y agoThat, and wash outs or fallen rocks can block the tracks.
