Power Saving at its best. All the lights installed on the newly built foot over bridge are monitored by motion sensors. The lights turn on when you stand beneath them and turn off only after you have passed and that too after a duration of 5 seconds.(I made a video with my friend, showing how this lights work but couldn't upload it here as I have to upload it on Youtube first). I know this is not a whole new concept but come on, having them installed shows how the railways is committed towards saving electricity.
