Hi,

I was in leicester square tube station today on the northern line waiting
for a tbe a guy appeared to have droped something on the tracks on the
first ledge I think it was. My heart skipped a beat when I saw him jump
down on the track to get it. A tube was soon coming in 2 mins. He jumped
back up and said its ok the first track is not live! after scaring many
people.

I have always thought all the lines are live?

Only the ones with insulators under them are live - the train runs on on the
other two, and simply rubs the other ones to get its juice. One is +630v
and the other is -210v (or the +/- the other way round )

No tube staff said or did anything one was a little up the platform,
didn't seem to bother him.

That's not a good sign! I'd at least expect them to tell him not to do it
