Perhaps only in the movies can we see about people accidentally (or intentionally) falling into rails or tracks, the likely outcome of which is of course death. In the real world, there are instances, most heard of in the Philippines and India. But the U-Bed may be something that could prevent such tragedies.
The U-Bed idea from Ruidong Wu is a safety bed nestled with a railway track system, a potential life-saving solution for countries which have growing railway-related accidents. This is a U-shaped roadbed which would be created within the sleepers of the track, something which can safely nestle would-be falling people, increasing the chances of survival.
